Note *x86* machines.  Given x86 has a global io address space I still
think this is true.

On some !x86 archs where a mmio window on the bridge is used for the io
address space multiple isa busses are possible.  I'm not sure whenever
this is purely theoretical or whenever such machines exist in practice
and in case of the latter whenever qemu can emulate one.

But in any case !x86 doesn't matter here ;)
