Can you try cherry-pick these two patches from stable/for-x86-3.3:
4f93aa02acd0e34806d4ac9c3a700bb5d040eab6

f474007a0761d0ecb6b84ceaf4f97f4f1de92038

and revert 8eaffa67b43e99ae581622c5133e20b0f48bcef1.

The easiest way is to do this:
git clone  git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git
cd xen
git cherry-pick 4f93aa02acd0e34806d4ac9c3a700bb5d040eab6
git cherry-pick f474007a0761d0ecb6b84ceaf4f97f4f1de92038
git revert 8eaffa67b43e99ae581622c5133e20b0f48bcef1

and then build the kernel and install it and such.

[What you are doing is removing the band-aid for the PAT
issue and adding in code that allows PAT to work]
