Just to note here also that I've today switched to apw's build of 3.2.0-23 [1] linked to from bug 922906. I had been running the upstream 3.3 for more than 7 weeks without hitting this (#917668). The GPU lockup I mentioned in #13 also never reoccurred since that one time.
I'll report back, should #917668 resurface with the kernel I'm currently running.
