I'd suggest your best bet to try to trace this would be to switch to
the open source nv driver for a while & see if the problem still
occurs. For 2D use, it's fine; it just lacks 3D and multihead support,
I believe.

Ouch. I have my machine set to sleep when the lid is closed, so this
doesn't happen. I don't like running laptops with the lid shut, even
when using an external screen - it often can cause overheating
problems, in my experience.
