dmesg log, 2.6.38 with commit 73412c3854c877e5f37ad944ee8977addde4d35a reverted

There's a regression introduced in kernel >=2.6.38-rc8. It's in nouveau/master
(commit 7972f91c24bb66643d76cf635faea78eb184e6b6) as well. Dmesg shows: "GPU
lockup - switching to software fbcon". I've done a git bisect. The problematic
commit is: 73412c3854c877e5f37ad944ee8977addde4d35a "drm/nouveau: allocate
kernel's notifier object at end of block". I reverted that commit on top of the
2.6.38 to confirm the issue.

Reproducible: always
