Rebuild your linux module.

cd /sys/modules/linux
make depend
make


If you've never loaded linux (and won't crash because of the bug),
then load the new module:

kldload ./linux.ko
kldunload linux

Else just install the module and reboot

cp linux.ko /boot/kernel/
shutdown -r now

Just apply John's patch.  Its cleaner & suitable for committing if it
works.   Mine was a quick hack while waiting for my dinner to
microwave itself..
