Haldane's dilemma has 242 mentions on Google Scholar - many in high profile journals. So it appears that many scientists have confidence that they have a solution - although you are always welcome to argue with their solutions (I am sure there is a thread on this site somewhere).
But even if you are correct, and Haldane's dilemma is a problem for current evolutionary theory, your options are
A. Modify evolutionary theory to allow the theory to explain the data - and show that the new theory still fits with the other evidence already published.
B. Come up with a completely new theory (creation theory, aliens, whatever) that can explain Haldane's dilemma and can also account for all the other lines of evidence.
There are probably 50 different lines of evidence supporting the argument that chimps and humans are related (gene similarities, non-coding genetic material, brain structures, locations of fossils, similarities in early human fossils, similarity in immune response, etc). If you want to argue that humans and chimps are not related, then you need to explain all these different lines of evidence (i.e., show how your theory accounts for these other converent findings). Do you want to start a thread on that?
Even if you were to find a weakness in evolutionary theory (find a piece of the puzzle that doesn't fit), you can not effectively argue for any alternative theory until you can show that the alternative theory does a better job at predicting the available evidence (can put the puzzle together in a completely different way with the available pieces).
Hope that helps,
James
p.s. I am confident that the majority of Christian biologists accept evolutionary theory - but I think can find a link, if you would like to see the survey data.
I will explain these different lines of evidence from my YEC point of view. You only list 6 so I will start with the 6 you listed.
Gene similarities & non-coding genetic material – The project Encyclopedia of DNA Elements (ENCODE) has recently published their findings of their analysis of 1% or 30 million bases of the human genome. They found that what they considered “junk” DNA is not “junk” after all it is transcribed into RNA and it is functional. It can no longer be considered non-coding as it was before. So with only 1% of the human genome for comparison the gene similarity went from 98.5% to 95% and estimations from researchers say it could reach as much as 80%. At 95% common ancestry is waning fast and should the percentage increase you can kiss common ancestry good-bye. In 2002 a study compared 77,461 chimp bacterial artificial chromosome (BAC) end sequences to that of the human sequences and found that only 48.6% of the human sequences matched the chimp sequences. In 1998 a study of structural differences between cell surfaces of chimps and humans it was discovered that a form of sialic acid (a kind of sugar) was not present in humans but was present on the chimps.
Brain structures – When comparing human and chimp expression of proteins of the brain and liver cells there was 31% difference in the levels of expression. When comparing human and chimp protein expressions there was above a 10-fold difference. Similarities seem to be diminishing.
Location of fossils & similarities in early human fossils – This is a good point if you map out where so called fossils are you will find that they are in locations were primates have and are living in abundance. As of now of the 12 so called hominid fossils 9 have been ruled as extinct primates. So they are just proving that there are a number of primate fossils found in an area that had and still does have primates living in that area. I have not heard about the other three as of yet I believe they are still investigating them. I would like to add a little more about Australopithecus Afarensis known as Lucy. This fossil received wide publicity as early hominid. Yet they never talked about the fact that Lucy was found in two separate digs over a mile apart and at different depths. However, that did not stop Johanson from putting the two together and saying they are from the same individual. There is somthing wrong when this kind of practise is done.
Similarity in the immune response – Medical News Today claims there is a significant difference between chimp and human immune cells yet they believe this difference will help in some way; however, I am not sure of that idea because of the following article. In a PCRM Research article Wendy Thacher, DVM, writes “There are many physiologic and anatomical differences between chimpanzees and humans. These differences make them a poor “model” for humans. Data obtained on chimpanzees cannot be extrapolated safely to the human situation.” The article goes on to explain the difference specifically. Aids is the first on the list stating that the antibodies T8 lymphocytes in a chimp respond more powerfully in chimps than humans. Next on the list is hepatitis B stating chimps become good hepatitis B carriers and do not display the suffering of the illness. There are several areas of difference listed and at the end of the article Thacher writes that chimps have too much difference to be used in human medical research.

I would like you to understand that I am just explaining this evidence not to win you over to creationism. Also I am not trying to disprove your evolutionistic views. I am explaining why I hold to my YEC beliefs. As far as the similarities that are there evolutionists look at the evidence and say common ancestor and YECers look at the evidence and say common design from the creator. It is your right and purgative to believe and preach without retaliation what ever you chose if it is evolution so be it and I will not tell you can not do this. I and my fellow YECists are asking for the same privilege from evolutionists. This is one of the reasons I like this form of debate those who want to talk about their differences in a peaceful manner can.
