Nothing other than the usual:

1) Make sure X is running in 16bpp - anything else dumps you to software rendering.
   I check using the 'KDE Control Center' tool - click on 'Information' then
   'X-Server'...there is probably a native X tool to do this.  Several times
   I've been suprised to find myself in 24 bpp mode despite asking 'startx' to
   put me in 16 bpp.
2) Either make sure that /dev/3dfx is installed and has rw-rw-rw permissions...or
   run your application as 'root'.
3) Don't demand stuff like stencil planes, alpha planes, etc.
   If you let GLUT pick the defaults you should be OK.
4) Don't forget to "setenv MESA_GLX_FX fullscreen".
5) Use 'ldd' to ensure your application is getting the libGL.so you expect it
   to get (not some weird shit floating around in /usr/local or /usr/X11R6/lib
   or someplace like that - and not libMesaGL.so or something).  If necessary
   use 'find' to track down all the leftover versions and 'rm' them just to be
   certain.
6) Use ldd to ensure that libGL.so is demanding libglide.so.

Does this latest version *have* to use DRI?  If so, then I'm out of my depth - but
I'd wonder whether I had the right modules loaded in XF86Config and whether I have
the right revision and type of X server (I guess if you already have 4.0 then that's
covered already).

This is all getting *WAY* too complicated!
