What kernel is this ?
The kernel syscall is supposed to return the proper iobase for the card
and does indeed handle uninorth properly, at least on 2.4. I have to check
what's up with 2.2 (didn't play with it for a long time).
The "ultimate" fix is however to implement davem /proc stuff properly.
this would probably require more hacking as even internally, the PPC kernel
is currently unable to properly do inx/outx-like IOs on anything but the
external PCI bus.
