Sorry for my late answer,

I tried to change the brightness using 
/sys/class/backlight/samsung/brightness directly and it works fine, 
although if I install gnome-power-manager I can change the brightness 
without any problems.
About the kernel : I'm using the linux-image-686-pae package (actual 
version is 3.0.0-1) should I try with a more recent one? (I've never 
compile a kernel before).
Furthermore it works fine with xbacklight in squeeze with the 2.6.32-5 
686 kernel.

Cheers,
Adrien
