What I meant to say was MSI works fine on bridges other than the
bridge the internal gfx lives on.  quirk_disable_msi() just disables
MSI on the devices on that particular bridge as far as I understand
it, but I'm by no means an expert on the PCI code.  E.g., on my RS780
board, MSIs are only problematic on the integrated gfx chip.  MSIs
work fine on PCI/PCIE add-on cards and the integrated Ethernet.
