@madbiologist: Honestly I had not tried using any 3D accelerated games with the default Open-Source Radeon driver because I assumed it would not work. But I just now tried extreme tux racer and it worked just fine. I guess the open-source 3D graphics driver architecture has advanced by leaps and bounds since the last time I tried to use it, at which point it did not work. (It actually wasn't THAT long ago that I tried to use it, but I'm still sure it's much older than what Ubuntu is currently using because it was on the stable version of Debian :p )
