ChangeSet 1.1159.256.62, 2005/03/19 20:36:50+00:00, kaf24@xxxxxxxxxxxxxxxxxxxx

        Allow domain0 to see PCI bridges. It should be able to deal with
        seeing PCI buses twice (once as a 'root bridge' from Xen; once by
        scanning behind a PCI-PCI bridge itself), and this gets rid of 
        problems where the bridge needs to be seen by XenLinux for drivers
        to work (e.g., Mellanox Infiniband chipsets).
