Is your machine even using the intel backlight device? You can test this
by:

# cd /sys/class/backlight/intel_backlight

Then look at 'max_brightness' and try echoing a range of numbers from 0
to max_brightness into the brightness file and see if it changes the
backlight.

It's more than possible that your machine is simply using some other
hardware to drive the backlight and that the integrated backlight
controller is simply disabled.
