Unfortunately, it seems that the patch does not fix the problem. I compiled 2.6.15-25.43 with the patch added, but with the same configuration, and it did not resolve the problem. I also tried the using the 2.6.17-2 from Edgy, and that also did not resolve the problem, so I am guessing that the patch doesn't fix the problem.
