Please, see attached patch. TODO:
1) Add METHOD (enum { ACPI, GPU, PLATFORM} ) as
backlight_device_register parameter
2) Add display name as backlight_device_register parameter
3) Use given METHODs in backlight_best_device
4) Fix symlinks to be created in /sys/class/backlight/ instead of
/sys/dev/char/ (how?!)

What about proposed solution?
