Thanks for that jeannich, it works really well (though I like to set -time 100 -steps 10 for smooth changing).

You still have to run these 2 lines after each reboot though:

:~$ xrandr --output LVDS --set BACKLIGHT_CONTROL native
:~$ sudo /etc/init.d/acpid restart

And GNOME does not recognise a change in backlight state.
