I have this hardware. 3D works (mostly), and has always worked out of
the box, as far as I can remember. That's why I love Ubuntu -- mostly
stuff just works.
I can run Compiz if I disable the "blur" plugin (which makes things
*too* slow) and if I also disable dual-monitor support (32 megs of video
RAM is not enough for a 3D desktop at 2304x1024, and besides the
hardware 3D engine only supports acceleration up to 2048x2048).

I see a lot of people tweaking obscure options to get the maximum FPS
value in glxgears. People I respect keep saying glxgears is not a good
benchmark, and the FPS it shows have little to do with the speed of
actual 3D applications/games.

That's interesting. I can run driconf and it doesn't complain.
If you run
$ glxinfo |grep direct
in a terminal, do you see "direct rendering: Yes"?

You don't need to.

If you want to trick a pointy-haired boss into letting you write software in
Lisp, you could try telling him it's XML.
