  The tdfx driver won't work without PIO support for now, for my machine
i mmap the right iobase but obviously this isn't going to work in other
machines so its not on much of use for other people.

I am working in fbdev support in the tdfx driver but its not ready yet
and fbdev doesn't make this easy at all, for example if tdfxfb uses
a hw cursor the fb memory you mmap starts at an offset and you have no
way to know what this offset is, the xdriver *has* to know this to
program the command fifo :(

You also need to tell the xserver which screens to use, here is what i use

Section "ServerLayout"
  Identifier "Main Layout"
  Screen "myScreen1"
  Screen "myScreen2" RightOf "myScreen1"

  InputDevice "Mouse1" "CorePointer"
  InputDevice "Keyboard1" "CoreKeyboard"
EndSection

  If the internal video doesn't isn't in /proc/pci then you have no
problem, the xserver won't detect the card so you can go away without the
BusID line.
