ACPI/Panic 2.6.8-rc3

[carbonated beverage]

Reported this a while ago, but tried it again, still getting oops
when doing an rmmod of the ACPI processor module.

Hardware: IBM T30, P4 2.4GHz, 256MiB, Debian/stable, did an rmmod processor.

Note: Oops below was copied by hand, so may not be fully reliable.  Also,
EIP was screwy, so no idea what was executing.

100% reproducible.
