xbacklight stopped working on Samsung N220

[Christian Mertes]

Since the last update I can no longer set the display brightness using the appropriate keys which in turn use xbacklight on openbox/LXDE/Lubuntu. setpci still works to set the backlight and also there is still a display of what xbacklight thinks the current backlight level to be when pressing the keys. It's just in no way correlated to the actual backlight level.
