The machine I tried to test doesn't intialize sub busses at all :(

This was a Noname - later machines route memory ranges and enable
io ranges without activating them on bridges.
Will have to retest with another box later.
How much work would it be to route resources our own?
I think you already do something like this for cardbus.
Interrupt routing is already active for that machine so I just need
memory and maybe io for stupid drivers/hardware, although io on alpha
is just another memory range.
