It works fine.

The patch from comment #8 doesn't help for gpm, though. It seems like the gpm
issue is related to two ACPI events being sent per key press. Gpm tries to set
the brightness itself on the second event (it doesn't act on the first one) to
a value not listed in the valid value table (_BCL) which causes the brightness
to drop to the lowest level (driven by the firmware I guess). Maybe the new
brightness should be validated in acpi_video_device_set_level (so the
validation should be moved from acpi_video_device_write_brightness to this
function)? If desired, I can provide a patch for that - I will play around with
that anyway.
