The issue isn't with PCI-PCI bridges on a PCI card but the PCI-PCI bridge that sits between the PCI slot *and* the PCI IDE controller on the 105 motherboard. I added a fix from NetBSD which helped with the PCI IDE controller but we still don't deal with anything sitting in the PCI slot, NO PCI cards will work, period.
