That's the case. I mean it should know all busses and does support all 3
uninorth busses. Is it called properly for the AGP bus (bus 0) by XFree ? 

My understanding was that XFree could only handle 1 IO base and so was
calling it only for the external PCI bus so that it can work with PCI-based
cards. 

The fact that outb seem to work and inb gives an error is normal, write
transactions rarely give an error as they are "posted" (buffered & delayed)
by the host bridge. That doesn't mean that your outb actually ended up to
the card.
