DRI device not having right permissions all the time

[nekromancer]

I have Gentoo-source 2.6.26-gentoo-r3 installed, including ati-drivers-8.542.
When I start xdm the /dev/dri/card0 always gets created with permission 660. And this causes problems when trying to access the dri device when I log in as a regular user in KDE.

I always have to chmod 666 /dev/dri/card0 for me to get direct rendering.

Is there some way to fix the permissions ? Right now I am just chmodding it 666 whenever I start xdm.

I have this in my xorg.conf
