I also get

PCI BIOS passed nonexistant PCI bus 1

How can this be? I configured the kernel with:

# CONFIG_PCI_GOBIOS is not set
CONFIG_PCI_GODIRECT=y

What is this option good for if Linux still listens to what the BIOS says?

How do you think we should go about IRQ routing
without reading BIOS tables? If you have a viable
solution, I'd be happy to listen to it.

Accessing PCI configuration space is trivial. Only two or
three ways actually exist on x86. The IRQ routing is different.
Every little motherboard vendor routes them differently.

It turned out to be an ACPI issue.

Darn. Not AGAIN!
ACPI is the biggest pile of crap to poison this earth.
I have yet to see it "just work".

I'll turn it off for good now, sorry for wasting your time with this.
