Doesn't the tdfx driver work?

  Beyond endianess problems the tdfx driver uses PIO which isn't
working under ppc right now (and unless the kernel people decide
on a way to export iobase to userland some time soon PIO might
take a while until it gets supported)

Can't we use the MMIO aperture to access the PIO registers?

  Most of the PIO registers are available under MMIO as well,
unfortunately the crtc registers (and a few others) are only
available in the PIO aperture :(
