Ok, so I have a patch that makes Intel mostly not suck now.  I haven't
really addressed the restart issue, but If your issue is occurring with
a clean STABLE, then it almost has to be vblank/irq related and that is
what I've been trying to fix.

Setting Option "NoTrapSignals" "on" in your xorg.conf should cause it to
drop core, which may provide some confirmation of what is going on.
