I have the following settings which I use for 9200 and 9250 cards in
xorg.conf:
Section "Module"
...
# This loads the GLX module
Load "glx"
# This loads the DRI module
Load "dri"
EndSection
...
Section "DRI"
Mode 0666
EndSection
...
Section "Device"
Identifier "Powercolor Radeon 9200"
Driver "radeon"
# Insert Clocks lines here if appropriate
Option "AGPMode" "4"
Option "EnablePageFlip" "on"
EndSection
For DRI to work it is also important that you have the agpgart module
loaded.
henca@balrog:~$ lsmod | grep agp
agpgart 42552 3

My guess is that you get this error because you are out of space on a
partition. It should not be related to your card.

With my 9200 I get:
14246 frames in 5.0 seconds = 2849.200 FPS
If I remember right I think the 9250 cards at work give about 2600 or
maybe 2400 fps. At work I have at least two different brands of 9250 cards
which gives a rather big difference in performance.
Another useful program is glxinfo:
henca@balrog:~$ glxinfo
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
Look for the line above to see that DRI is enabled. If you get a "No"
instead you could search for explanations in your Xorg.0.log.
