I don't think MSI is supported by Linux on ppc64 right now.  In fact I
don't think you can even select CONFIG_PCI_MSI.

I'm not sure what ppc64 hardware can even do MSI.  For example IBM
JS20 blades use the AMD 8131 for their PCI-X bridge, and we know that
part doesn't support MSI.  I believe Apple G5 hardware uses the same
chip for its PCI-X slots.  On the other hand, all I see from lspci on
a p630 system is

    PCI bridge: IBM: Unknown device 0188 (rev 02)

so who knows what that might do?
