ATI AIW Rage Pro, + OpenGL

[Niyamas]

Heyo. Can anyone point me in the right direction on getting OpenGL 
running smoothing with a rage pro based ATI card? GL runs, but it's 
terribly slow. I'm running 5.3, and just want to get xscreensaver 
working decently with the GL screen savers. I think it's got 16 megs on 
it, maybe 32... not more than that, though. Am I asking too much out of 
this card? The PC is a dual P3 1.0ghz box with 512 megs RAM, and GL ran 
fine on it under windows... wasn't the youngest girl at the ball, but 
she still turned a head or two. Are there any good walkthroughs in 
getting GL running better?
