One trivial thing to try would be to just bisect it. I assume 2.6.26 is 
fine, so while it will take a few boots to try it out (there's 8111 
commits in between, so 13 reboots should do it), the advantage of 
bisection is that it's fairly straightforward to do even if you don't have 
any clue where the problem might lurk.

And with your machine, recompiling the kernel 13 times shouldn't take that 
long ;)
