Well, good guess, that did the trick (almost). I added radeon to 
/etc/modules, now the module seems to be loaded early enough:

# glxinfo |egrep -i "render|vendor|direct"
direct rendering: Yes
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RS880 9714) 20090101 
x86/MMX+/3DNow!+/SSE2 TCL DRI2

!!!--- full render string, not software rasterizer!

root at linux:/home/frisco# cat /etc/modprobe.d/radeon-kms.conf
options radeon modeset=1
options radeon agpmode=-1
options radeon dynclks=1

Should I try to leave the last two lines away to get better performance?

But performance is still slow - I know glxgears is no benchmark, but I 
get 850FPS without KMS - maybe because of agpmode=-1?

$ glxgears
2396 frames in 5.0 seconds = 479.110 FPS
2841 frames in 5.0 seconds = 568.051 FPS
2828 frames in 5.0 seconds = 565.438 FPS

And btw, System Settings in KDE tells me "Compositing is not supported 
on your system".

So s.th. still missing, right?

Thanks for your great help so far,
Cheers!
