You surely know, but just in case you can put this line into your $HOME/.bashrc:

alias bri='sudo setpci -s 00:02.0 F4.B=CC'

After that you will only have to type bri and enter your password.

Back to the topic, this is more Samsung's fault as these buttons don't work in Windows 7 without special drivers.
This means the scan codes of these buttons are not standard (I know there's no official standard, but consensus).
GNOME does have shortcuts for adjusting brightness which work on most other laptops.
