Glide and GGI?
A GGI driver for Glide is under development by Jon M. Taylor, but has not officially been released and was put on hold till completion of GGI 0.0.9. For information about GGI see synergy.caltech.edu/~ggi/. If you are adventurous, you might find the combination of XGGI (a GGI based X Server for XFree86) and GGI for Glide an interesting prospect. There is also a GGI driver interfacing the OpenGL API; tested with unaccelerated Mesa. Essentially, this means X11R6 running on a Voodoo Graphics ™, using either Mesa or Glide directly.
