All IBM -> hardware for volume.  Firmware (we don't know how to turn it off
on all GPUs) for brightness, brigtness is controlled by the EC, so it HAS to
be done through thinkpad-acpi AFAIK.

Lenovo:  I don't know for the Z-series.  T60: depends on BIOS revision.  All
others: Volume -> software, except for MUTE, BIOS helps thinkpad-acpi don't
get confused. Brightness -> software, but you need to tell the BIOS to hand
over brightness control to the O.S.

It will be done by the DRM layer, but work is still under way.

X will have to special-case the keys for that to work on Lenovo models.  It
is as simple as that.  IBM models special-case it it firmware anyway, so it
is easier.
