Having direct rendering enabled is not enough to determine if 3D acceleration is working. You really need to check the OpenGL renderer string as well:

Code:
glxinfo | grep -i render
Having said that, you probably do have 3D acceleration enabled. Your Xorg log file does look good and 3D acceleration should be working on your GPU out of the box. It's quite possible, however, that the video card and drivers just aren't capable of decent acceleration. The Xpress 200 GPUs are rather low-end, as far as mobile GPUs go.

You could run supertuxkart with the environmental variable LIBGL_DEBUG enabled:

Code:
LIBGL_DEBUG=verbose supertuxkart
This will print a few lines of debugging information which would let you know if there's some other problem with your driver setup.

O-K, here's the OpenGL rendering string: (I can't tell from this if the 3D is on)

Code:
direct rendering: Yes
OpenGL renderer string: Mesa DRI R300 (RS400 5A61) 20090101 x86/MMX/SSE2 NO-TCL DRI2
And here is the debug info (Game opens, and race starts...but graphics are still scrambled- seems to show a problem here...but how to fix it?)

Code:
 LIBGL_DEBUG=verbose supertuxkart
Data files will be fetched from: '/usr/share/games/supertuxkart/'
SDL_LoadWAV() failed to load /usr/share/games/supertuxkart//data/sfx/horn.wav
Highscores will be saved in '/home/bob/.supertuxkart/highscore.data'.
libGL: OpenDriver: trying /usr/lib/dri/tls/r300_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r300_dri.so
libGL: Can't open configuration file /etc/drirc: No such file or directory.
libGL: Can't open configuration file /home/bob/.drirc: No such file or directory.
(((The one good thing about having problems = I learn an awful lot with youse guys helping me fix them. You're not just helping me fix a game...you're helping me to learn about Linux!)))

Well your glxinfo shows that you are using the Mesa r300 driver, which means you have 3D acceleration. And the output from supertuxkart, with LIBGL_DEBUG set to verbose, shows it loading the r300_dri driver as well.

So you have either hit a bug in the game, a bug in the driver, or just a limitation of the hardware.

You could try booting with the 'nomodeset' option to the kernel. This will disable kernel modesetting, as well as DRI2, and might give better results.
