Same here for a Dell, an IBM and a Lenovo laptop: The brightness
keys are "hard-wired" and act without OS interaction, whereas the
multimedia keys are "normal" keys (check with "xev" program) and
can be programmed to do anything (like issuing "mixer" commands).

Sometimes you can adjust brightness in BIOS setup. If you don't
need to change brightness all the time, this seems to be the
most comfortable situation.
