Voodoo4/5 has a different method of byte-swizzling for big-endian hardware than the Voodoo3 - which isn't supported by the current tdxfb driver or by XFree86. I have been working on a fix for tdfxfb, and have had some success - but since I don't have any documentation, it's involved a lot of guess-work. I haven't looked at this for a while, but I could dig out the code again and supply a patch against what I have got so far.
As to your other problem, I have two Voodoos working on my Mac with 2.6, so I would expect such a set-up to work on the Pegasos too. On PPC hardware, there should be no problem of conflicting VGA ports since the PCI sub-system can remap I/O ports on the PPC.
Actually, there are one or two bugs in the tdfxfb driver which crop up when
using multiple cards - but nothing too serious it would seem. Again, I've been meaning to submit a patch . . . (where does all the time go ;-)
Cheers,
Rich
