Radeon 7000 3d ?

Hi all, I bought a radeon 7000 cheaply today, for my other pc. I was going to use this card for windows stuff( dreamweaver ) and maybe a few games. However ... This card has dual outputs so I thought Id see how it would be for a linux box, maybe I'll use it for my work machine. Suse 7.3 installed like a dream, and up popped a nicely setup 2d x. but. If I run /usr/bin/gears framerate is 136 not good. How do I enable the 3d part of the card in 7.3 ?? dids
