I believe the right way to cope is adding the devices with the right
unit number.  I think anything else is doomed to failure.

However, it will mean that we'll need to OMIT the sio hints for ISA
when we do acpi.  We shouldn't be loading hints for isa anymore
anyway, except on really really old machines.
