Problem: Function keys don't control de backlight brightness and can't
be controled by System Configuration either.
With stock Ubutnu distribution (both kernel and Xorg server) I get this:
No entries in /sys/class/backlight whit or withtout
"acpi_backlight=vendor" grub line
Low level setpci command works
$ sudo setpci -s "00:02.0" F4.B="XX"
Where "XX" is anything between 00 and FF
On dmesg when pressing keyboard funciton keys:
Fn+F3 (Bright UP)
[17431.095998] atkbd serio0: Unknown key pressed (translated set 2, code 0xab
on isa0060/serio0).
[17431.096022] atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.

With mainline kernel 3.3.6 and Xorg-Edgers PPA is the same
