Hi,
3d Acceleration here on my Radeon 7500 was not as much a problem,
I am using, the X11 radeon module from a recent 2.6.0-rc2 kernel.
I am using debian here.
I installed
xlibmesa-gl1-dri-trunk - Mesa 3D graphics library [DRI trunk]
xserver-xfree86-dri-trunk - The XFree86 X server [DRI trunk]
from
deb http://people.debian.org/~daenzer/dri-trunk-sid/ ./
I did not build the modules, i used the untouched radeon from the kernel.
here is the output from glxinfo:
visual x bf lv rg d st colorbuffer ax dp st accumbuffer ms cav
id dep cl sp sz l ci b ro r g b a bf th cl r g b a ns b eat

glxgears output in 16bit 1024x768:
fritsch@todesstern:~$ glxgears
4518 frames in 5.0 seconds = 903.600 FPS

I think you should get better results with your Radeon 9000
