It's been a while so I figured a little update on this situation might be appropriate.
I have not experienced any issues for a very very long time. I can't remember the last time I had this crash happen, so I can only assume that driver/firmware updates have managed to either eliminate the problem or make it sufficiently rare. Starcraft 2 used to trigger this crash on my system somewhat frequently, but I have been playing SC2 at least once per week for months, and there's not been a single crash.
