I could help you to debug your AT3D code because I have a working Linux setup 
with that card (Alliance based voodoo Rush).
I managed to compile Glide 3 and Mesa 6.2.1 (commenting out some AT3D code).
But, of course, it segfaults on exec.

That is a funny thing. It seems that no one really has used the code for years.
I could say that even apm XFree module doesn't work from version 4.0.1 onwards.
I had to switch back to XFree 3.3.6 release to be able to get video.
There is also a library (libXxf86rush) that has not been used for years, and is
causing problem to some people compiling Xorg, although it is pretty useless 
nowadays. That is the problem of legacy code that is kept from previus 
releases and supposed to work but never tested.

I think that is better to state from the beginning "this shouldn't work with 
that hardware" and remove code and support than let the users face a painful 
and hopeless testing work.

But if you want make work for the first time the Voodoo Rush with Linux (I mean 
Open Source Glide / Mesa > 3.4.2) I am ready to help.
