OK. So what's the realistic solution?

The best I can think of is something like this (see attachment).

It's not perfect, because if someone inserts a VIA PCI card into a 
VIA-based motherboard, the quirk will also run on that VIA PCI card.
Is there a way we can realistically say "this is an on-board device" vs 
"this is a PCI card"?

This is untested but I'll happily test and work on it further if it 
doesn't get shot down :)
I have only added the southbridges for my own hardware and the one 
listed on the Gentoo bug. I guess there will be more. I also wonder if 
listing the southbridges is the most sensible approach or if other 
devices (e.g. the host bridge at 00:00.0) would be more appropriate?
