It would almost certainly break some other machine. We could, of course,
use a quirk to make your machine work, but that's something of a
last-resort as it won't fix any other machines.

Ok, so the new native backlight driver works, but conflicts with your
previous backlight driver (whatever that was). Adding support for the
native backlight driver (Matthew's patch) and disabling the old
backlight mechanisms makes everything better. Right?
