Reverting this single commit on top of kernel 3.5-rc5 fixes the problem for me. Jure, Jonathon and everyone else hitting this issue, please try reverting 416a2bd274566a6f607a271f524b2dc0b84d9106 and report whether it helped or not. At least this will tell us if my problem is really the same as yours.

There are tons of things that could cause a GPU lock up (kernel issue, userspace issue, or some bad combination of kernel and userspace bits). 416a2bd274566a6f607 is only a month or so old so it's not related to the original bug report and should probably be reported as a separate issue.
