Some segments of the Linux user community, which prefer to avoid the IP-encumbered ATI drivers due to ideological choices, still prefer the R200-based chips, as they are among the fastest modern video cards with stable open source drivers. (source)
My ATI RV280 Radeon 9200 works great with The new Compiz window manager that comes with Fedora Core 6. Using the
desktop-effects program, you can replace the old window manager (Metacity) with Compiz. Compiz makes use of neat effects such as the spinning cube and the scaler plugin (similar to OSX's exposé).
For once, something just works.
gconftool-2 --type bool \ /apps/compiz/plugins/cube/screen0/options/in \ --set true
Compiz has more options. It's a bit of a kludge ot change them.
