I believe that I've got a similar problem with amdsbwd(4).
It needs some resources (I/O ports) that belong to ACPI.
The problem is that the driver attaches to isa bus which is under
isab->pci->pcib and those particular resources are not assigned to the Host-PCI
bridge.

I think that you already made a suggestion that perhaps isa bus should  directly
attach to acpi bus when acpi is available.  Not sure if there are any
alternative approaches.
