I finally got annoyed at the fact that Mac OS X likes to reprogram the
keyboard controller such that, on by iBook (dual USB), F1-F6 and F12
send "button" events (adjust volume, adjust brightness, eject, etc),
since I use F-keys to switch windows under X in NetBSD. Not knowing
how to reprogram the keyboard controller back (Mac OS 9 can do it, but
it's undone most times I boot into OS X), I came up with this patch
which takes the button events and turns them back into keyboard
events.

Comments?
