wtf? So the memory at d094ee7c (which contains i810fb's pci table) became
unmapped from kernel virtual address space as a result of you inserting
your carbus card.

I am impressed.

Jsut as a crazy test, could you delete /sbin/rmmod and see if it still
happens? Maybe something is removing the module at an embarrassing time or
something.
