--- Comment #13 from Alex Deucher agd5f@yahoo.com --- The audio hardware doesn't interact with the memory controller (or 3D engine for that matter) so I don't really see how it could cause a GPU page fault. Also, the fact that disabling audio on a newer kernel doesn't break things leads me to believe it's not related to the audio at all. Maybe some stale mesa stuff floating around on your system? Nothing else really comes to mind.
