Delyan, are you able to force the NVIDIA proprietary driver to control the backlight? You can do this by adding

Option "RegistryDwords" "EnableBrightnessControl=1

to the "Devices" section of xorg.conf and then restarting. Also, does your backlight emit a buzz or humming noise when the brightness has been changed using the NVIDIA drivers?
