G5 and IO accesses

[Benjamin Herrenschmidt]

Hi !

I've heard in the past that people had trouble getting PCI cards
with IO ports (inX/outX) to work on G5s... looking at the setup code
today, it looks like I had a bogus base address when setting it up,
can somebody with such a card confirm that it works with this patch ?
