The same happens to me with a Radeon 9250. When a 3d app pops up, xorg freezes. (I must say that I experienced freezes with an ATI X600 at work, too)
My system is an updated Gutsy tribe 5. I solved the issue downgrading to xserver-xorg-video-ati_6.6.3-2ubuntu6_i386.deb from Feisty. So it's a regression! Deleting xorg.conf was not useful. Now desktop effects, games, 3D and so on, work perfectly. No freezes anymore.
