You do NOT care about bus numbers on the primary segment of a given
PCI domain. These are type 0 config cycles and so do not carry any
kind of bus numbers.
If the host bridge do try to muck with those, then it's not fully
on spec, but then, that can be worked around.
I'd still like to see the docs of this chipset though...
