You are right. The only cards/chips for which XFree86 GLX source
is available right now are the Matrox G[24]00 and the Riva TNT.

Because traditionally Mesa has not used GLX at all, instead rendering
frames in the application, whereas SGI clients have depended on the
X server having the renderer.

The way Mesa-with-GLX is currently built, it too is an either/or
thing - it has no way of falling back to rendering itself if the
X server has no GLX extension.
