I'm working on this. (I have one of the affected machines at > the moment) I noticed the NetBSD PCI fixup code just assigns the IRQ of the bridge to all card underneath it. I don't know how valid that is: does the bridge chip have A/B/C/D IRQ's assigned ? You may have to work out the bus numbers of the devices underneath and assume standard PCI mapping to work out which of the bridge IRQs to use. later, Peter.
