Yes. They are both OF cards and both are initialized by OF. Your cards have a
VGA BIOS? Well, I guess that shouldn't be a problem. The Peggy's BIOS
emulator must be able to cope with I/O ports not being in the usual (x86)
place - because chances are they won't be anyway even for a single card. Does
the Pegasos boot the BIOS on a secondardy gfx card automatically? If not,
you're back to the usual x86 problem of having to soft-boot the BIOS
yourself. Which will be a problem for you because I suppose the BIOS emulator
isn't accessible post-boot. However, it should be possible to initialize a
second Voodoo card without using its BIOS, but I've no idea how easy or
difficult that might be. Fun and games. ;-)

Of course, you have to get 2.6 working first or hack the 2.4 driver for
multi-head support . . .

Cheers,
Rich
