Hmmm... Mine has an entry for card0:

GentooPenguin# ls -l /dev/dri

crw-rw---- 1 root video 226, 0 2010-04-08 17:42 card0

Are you sure your opengl libraries are being found in /usr/lib/opengl?

I used to run the ATI proprietary driver and switched to the open Radeon
driver and remember some fiddling was required in this directory,
possibly a symlink pointing in the wrong direction.

What does the command "eselect opengl list" show you?

Mine tells me that the xorg-x11 driver is being used.

I get:

1438 frames in 5.0 seconds = 287.483 FPS

Not really screaming along, but adequate for my needs.
