Yes. So long as linux can find it. We just put it at bus 0 as convenience so we can find it easily. Putting the hypertransport chains on their own bus is clearer reflection of reality than putting extra devices on bus 0. > I think to remember that Linux wants the IO Hub to hang off bus 0 as > well.

Mostly that is a matter of putting the bus in the pirq table so linux will know about the bus.
