Could you try recent X.org intel driver release? Your failure X log showed some pretty old UMS driver's render flush time out message, I think whose version never has been well tested with new kms/gem stuff.

Could you bisect? I doubt it's caused by David's patch, as if it is, you will have trouble at early agp init time, instead of current problem looks like something causing rendering hang..and I can't think of how mapping GTT to a scratch page could cause problem in case GTT bar is truely 256K.
