I've done some quick (read slow) testing with extremetuxracer and I get
(drum roll please) less than 3.0 FPS.  That's right, it's usually around
2.6 or 2.7, but did max out at 3.0 just once (in about 10 seconds of
fooling around, but it was clear things weren't about to get any
better).

Other information people have asked me to gather includes:

[rodd mythtv ~]$ glxinfo | grep -i direct
direct rendering: Yes
[rodd mythtv ~]$ xdriinfo
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
Screen 0: not direct rendering capable.
[rodd mythtv ~]$ 


It appears that glxinfo and xdriinfo can't quite agree.

I couldn't find teapot to run it.
