If your BIOS allows you to disable APIC, try that. If not, try booting the
kernel with the "noapic" option on the command line. Either way, this looks
like a generic kernel bug (or BIOS/firmware/hardware bug being tickled by the
kernel), not a restricted-modules bug. nvidia isn't hotplugged, and the fact
that it's an nVidia video card that appears to tickle this is a red herring, I'm
sure. Probably anything eating AGP memory would do the same, at a guess.
