For the lockup itself I have filed:
https://bugs.freedesktop.org/show_bug.cgi?id=45329

The kernel regression has been partly addressed by:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=9fc04b503df9a34ec1a691225445c5b7dfd022e7

The mutex deadlock has been fixed, but X still fails to recover from the GPU
lockup. With kernel 3.1 or 3.2 I didn't even noticed that these lockups where
happening.

See http://marc.info/?l=linux-kernel&m=132739068529857&w=2 for a SysRq+W
backtrace of the stuck X process
