Hi,

I have the problem too with -rc1, and even with latest linus tree.

I too bisected back to:
"agp/intel: Remove confusion of stolen entries not stolen memory)"
(c64f7ba5f1006d8c20eacafecf98d4d00a6902a0)

Symptom is I see a big vertical cursor blinking in my screen and
nothing else. If something tries to be displayed it gets very messy.
