Are you sure you've got the right commit? That shouldn't change the
calculation that's failing at all. I'd guess it's probably one of
these:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d33ef52d9db8a36900dd53f2e32db9a521ace259

Can you attach your xorg log as well?
