There's obviously a difference in bus enumeration here. Also,
NetBSD has a 'bus 1' twice, which is not good.
Also, looking at the FreeBSD info, I/O space is enabled and valid
on that PCI bus.
So clearly, PCI bus enumeration is the problem here.
I'm not sure how this can be fixed quickly. Another special purpose
hack that just says 'there are 4 PCI busses, and I'm ignoring the
pchbs' might work. I'll bake some new floppies.
