Cool. :)

The parts you ifdeffed from vio_bus_init() could be split into their own
vio_arch_bus_init() couldn't they? Then ifdef the definition of that. Or make
a vio_pseries_bus_init() and ifdef the call. Either way is just a little less
mid-function ifdefs, which is probably a good thing.

iSeries is a bit of a mystery to me still. :) I guess you don't ever call
vio_register_*() then...

I thought iSeries had its own vio_disable_interrupts()? Can't find it now, so
maybe I'm misremembering. If it does though, that could be moved to vio.c as
