Works here (Xfce 4.8.3 on ArchLinux, Asus Laptop)

Does it work with the lcd brightness plugin for the Xfce panel [1] ?

You might also be able to assign [Fn] keys (or others) to two custom 
console commands that will lower/maximize the brightness in Settings 
Manager -> Keyboard -> Application Shortcuts.
I forgot which command line tool can do it (xbacklight, maybe ?). There 
may be several ways.
