macallan 82ce0b1388 A driver for 3Dfx Voodoo3 graphics boards, may or may not work with Voodoo4,
Voodoo5 or Banshee boards.

So far it supports:
- full acceleration in 8bit graphics mode
- video mode switching
- virtual consoles via vcons

So far it hasn't been tested on anything else than macppc and even there it
needs a hack to overload ofb.

TODO:
- test on i386
- don't hardcode video mode
