Which makes sense, as volume/eject keys are no big diff at the moment, but, as Michael Schmitz pointed out, the backlight-related changes should not be introduced under the table.

Apparently the power key is already merged, as it shows up just fine in
evtest, the only problem (to make it handled by keyevd) is that it is on
another input device (ADB Keyboard instead of ADB Buttons). Moving it to
the ADB buttons would make it handlable.

With your patch (and the eject button added in the mac_hid.c table), the
eject button doesn't show up either in evtest or in keyevd. And the
brightness controls are of no effect, although the events are caught
