Hi, I also own this card and It's running fine.
Don't expect a lot of FPS when playing to 3D games though. This card is sufficient for Compiz but not really much more.
The next release of mesa will improve the situation, I've recompiled it and I get an average of 40 fps at a 1024*768 resolution when running Smokin' Guns.
My problem is that the card is not very powerful enough to fully support my 26" screen :s.
