FYI the combination of gnome-power-manager, gnome-screensaver and HAL
does this already. It should be trivial to use this from other desktop
environments too as setting (and getting) the brightness for back light
for the LCD is carried out through an extensible abstract interface in
HAL. Right now I think the interface supports IBM Thinkpad, Apple
Powerbook + iBook, Toshiba, Panasonic, Asus, Sony. We take patches for
other laptops. Btw, I do wonder if the X.org server should provide this
interface instead.

HTH,
