[gpm] how to leave screen brightness handling to the BIOS

[Guido Berhoerster <guido+gnome org berhoerster name>]

Hello,

how can g-p-m be told to leave screen brightness to the BIOS when xrandr 
is used instead of HAL, i.e. what is the equivalent of setting 
laptop_panel.brightness_in_hardware to true with HAL?
There seems to be a problem with Ubuntu 9.10 on MSI Wind Netbooks which 
appear to handle the brightness-related keyboard events in BIOS but 
still emit keypresses 
(https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/415023/).
