Grant,

Can you give me more details on why you say the opb_pci bridge is badly
broken?  I know there have been issues with it in the past, but I'm not
aware of major outages (perhaps I'm just not in the loop).

The opb_pci and plb_pci (plbv34) bridges have transitioned to the
plbv36_pci bridge in EDK 9.2 and later.  This bridge is fully supported
and has been tested under MontaVista's 2.6.10 kernel.  I believe only
critical issues will be fixed in the opb/plbv34.

Thanks,
Rick
