Uh, yeah. I could have told this had I known you were working on it...

GLX is an extension to the X server, part of which (I think) requires
support in the driver. Oh, the driver also needs to be able to use your

If you don't have hardware acceleration, mesa software rendering will be
used. Before you start looking, mesa is a part of XFree86/Xorg

Actually, it's even more complex. For some reason, some drivers support
GLXChooseFBConfig, although they claim to be GLX v1.2. This has led to
GLXChooseFBConfig being used indiscriminately. And while you can check
whether a specific function is supported, a patch for just that won't
do it. You still need to provide an alternative code path for selecting
a matching visual.
