I have seen this on my T61 with GM965, the thinkpad was running on battery and probably the screensaver (dont remember which one, but defnitely a 3D/GL based) was running at that point. The screen was totally garbled and the keyboard and the mouse dint work either. I havent reproduced this. But seems like the same issue. The OS is Hardy Release Candidate.
