Rusty rewrote the module loader in 2.6, the kdb rmmod command was
disabled during that rewrite.  The new rmmod tries to stop the system
and wait for the refcount to go to zero.  That is not going to work
with kdb, because kdb has already stopped the system.  Trying to rmmod
from kdb is almost guaranteed to deadlock.  So I never added kdb rmmod
back for 2.6.
