I'm not sure it's an underrun or anything like that: the corruption is
long-term in the non-video case. So I take back the "looks like memory
bandwidth problems", because it really looks more like a corrupted
blit operation there.

DVI on the Core i5, plain analog VGA on the sandybridge one (I can
hear you asking "Why?". Because the silly intel motherboard doesn't
_have_ DVI out, and I didn't have a hdmi cable)

See above. It's long-term, it was just the video behavior that made me
originally think it was temporary.

Will do. I'll have to reboot to the broken kernel (my bisection ended
in a non-broken case)
