I need help debugging a random lockup

[Marshall Lewis]

Did end up verifying the cpu temp and it was pretty low (under 40 deg
C).  Kinda stuck on the NVidia driver thing though, it's a dual-head
setup, and I'm way to used to actually using both monitors : ) .. the nv
driver apparently doesn't support dual-head on a single card.

Additionally I was wrong about it not locking up at home.. I've managed
to get it to happen twice so far today (that's an ATI card using the
driver that comes with xorg).

I had tried swapping the power supply at work, but it didn't make a
difference (still locks up).

I'm fairly convinced that it has to do with running 32-bit apps, because
it only seems to happen then (primarily FireFox and OpenOffice).
