That's a bug in the 2.4 kernel keyboard driver, it works under 2.5 but
the modifications are too heavy to be backported it seems.
They may be a quick and dirty hack (untested) if it bothers you and you
compile your kernel: edit the table e0_keys in drivers/macintosh/mac_hid.c
to put KEY_BRIGHTNESSUP and KEY_BRIGHTNESS_DOWN in the right place.
