I am not sure about gdm, but I use xdm, and adding 'xbacklight -set <val>' to
my login manager's Xsetup file did the trick.
I have a xdm theme, so the location is /etc/X11/xdm/archlinux/Xsetup.

You just have to find out your login manager's X init scripts location and add all
that you want to Xsetup.
