Sorry guys, that's not entirely correct. It IS the case when the Voodoo2 is
used in a PC, but if you read the links I sent before, the HP is able to use
it as a fully-fledged video card.
Here's a brief description of the reason from one of the mailing lists:
Moreover most graphics card require to be initialised by a PC BIOS (using
ix86 instructions). For that reason XFree86 comes with a small Intel
emulator that does the initialisation on non-Intel architectures.
The linux kernel does not do this and the Linux Framebuffer device drivers
for Voodoo,Radeon, Nvidia etc. won't work on non-Intel architectures for
that reason (unless a graphics card can and is initialised by some
other method not involving/requiring a PC BIOS. These cards are rather
rare and usually older graphics cards or plain framebuffers).
Some people try to get Voodoo2 running on a C2xx because this kind of card
is one of the exceptions mentioned above: it doesn't need to be
initialised by the BIOS, you can use glide for that (which is available
