every DDX does its own thing, and the dumb KMS API does not include it.
For example, xf86-video-intel has a list of paths to probe in /sys/class/backlight
(one for each major HW maker, and then some).
We can't do the same because we're not root.
It might be best to leave backlight out of the story and rely on the setuid
helper in gnome-settings-daemon.
