I also have a Thinkpad X201, with the same problem, with the same dmesg output as earlier in the thread. In an attempt to isolate the problem, I tried the following kernel versions:
mainline 2.6.32.9 -- works mainline 2.6.32.12 -- works ubuntu 2.6.32-14.20 -- works ubuntu 2.6.32-15.22 -- works mainline 2.6.33.1 -- doesn't work ubuntu 2.6.32-16.25 -- doesn't work ubuntu 2.6.32-22.33 -- doesn't work mainline edge -- doesn't work Turns out -14.20 wasn't the last ubuntu kernel to work. I wasn't able to get my hands on debs for ubuntu 2.6.32-16.23, but I suspect it wouldn't work as well. Looking at all the changelogs, all this points to the update to DRM .33 as the culprit. But that is a big patch, and I'm totally out of my league.
