I am first going
to attempt to see if I can route interrupts at least on the host-bridge
(at the moment my test box can't even do that!), after that I am going
to explore the PCI BIOS a bit (but I expect I'll have to write it off
like everyone else has).

I'm not sure, but perhaps the NetBSD PCI IRQ fixup code can be handy in this matter. It doesn't use ACPI (that's another kernel option), so it looks like it's pretty much what we need.

    In anycase, its messy stuff.  The existing code is virtually undocumented
    and contains a huge number of assumptions, special cases, and hacks,
    mainly because I think nobody *ELSE* understood it when it was modified
    in the past.

The fact that a lot of hardware manufacturers don't either doesn't help as well :P.
