Public bug reported:
I have a Dell Inspiron 600m with a 32MB Radeon 9000m, which uses r200
DRI. It has a 1400x1050 display, which with that little video RAM means
I always disable compiz, and use metacity instead.
As of 9.04, the DRI has gotten very slow. Switching tabs in Firefox can
take up to 6 seconds, if I run fullscreen.
p...@pat-laptop:~$ xdriinfo
Screen 0: r200
DRI appears to be running correctly, from Xorg.0.log:

I think there is a problem with memory mapping this r200. Running SDL
games is very slow and choppy. For example, supertux2 runs at about
2fps. The console for supertux2 shows the following after every frame is
drawn:
[driAllocateTexture:635] unable to allocate texture
This is what leads me to believe there is a problem with libdrm.
