Yeah, same here. I tried to bisect the damn thing but didn't find any
single commit. I think the problem was introduced in in the DRM merge
between 2.6.31 and 2.6.32-rc1. Some people suggested privately that it
might be related to frame buffer compression. Unfortunately I wasn't
able to revert that particular patch.
