bus allocation

[Stefan Reinauer]

Hi,

the bus allocation is currently very different from what older LinuxBIOS
trees and Phoenix/Award BIOS do. One obvious change is that Bus 0 has no
devices except the CPUs, bus 1 contains the 8151/8131 and 8111, bus2 the
pci/agp bus behind the bridge on bus1 etc. 

I wonder whether this can cause trouble. Does hardware expect the bus to
be arranged in a certain way? i.e. all 8111 devices before the agp bus
or similar?

I found that the solo dies right before it should do PNP SuperIO
enumeration:
