Nifty. Well, there's a few places to look for information.

If you're not sure how the actual video card works,
http://www.x.org/wiki/Development/Documentation/HowVideoCardsWork is a
great starting point. Of particular interest is the 3D engine; r300g
only talks to the 3D part of the video card.

The reference Gallium driver is probably identity, although softpipe
is a good reference as well. We also have documentation for the
Gallium API and associated bits; if you don't want to build it
yourself from the Mesa tree, there should be an up-to-date copy at
http://people.freedesktop.org/~csimpson/gallium-docs/. (If there's a
problem with the documentation, lemme know!)
