I thought this at first too, so I took the computer apart and blew it out
with my air compressor.  I reseated the cpu heatsink with a fresh batch of
thermal grease (and found that I had done it wrong to begin with, now it's
covering the whole top of the processor); I thought for sure this was
it, but then it continued to crash.  I implemented sensord to watch the
temps and I logged it every 5 minutes so I could see if the temps were
peaking when it crashed.  Alas, they were not.
