We ruled out ivtv, good for us but not for you :-(

Can you try to unload the ivtvfb module via "modprobe -r ivtvfb" and check:
  if this produces anything in the logs?
  does it also lock the machibe up, imediatly or again at shutdown?

If you have closed source modules loaded could you disale them and see
if it still locks up?

It there any backtrace or error message just before it locks in the kernel log?

Swapping the card to a different slot and check if the slot/cards is dusty.
