Will you please check whether there exists the ACPI generic backlight
I/F under the /sys/class/backlight/acpi_video0/*? If exists, please
check whether the backlight can be controlled by using the sys ACPI I/f.
   for example: echo 5 > /sys/class/backlight/*/brightness
   (Of course you had better test it under the X environment. And you
should assure that the acpi video driver is loaded).

Will you please attach the output of acpidump?
