I've got it working!

In the end I looked at my XF86Config file, and looked at the Identifier
label in the Device section (and the subsequent Device entry in the
Screen section), and I had spaces and things in there that I realised
might confuse things slightly, so I changed them to a simpler label
that wouldn't confuse things at all.

Fired up X, fired up tuxracer, and got a steady 12 or 13 fps at
640*480*16. glxgears now gives me around 290fps, and glquake runs very,
very nicely. To put that in perspective with your system, I have an
AthlonXP1400.

So I'm a very happy man :)  Thanks for the suggestions folks, I'm off
to play quake for a bit  :)
