Err, I still don't think I'm catching your drift but let me stop you
right there: amd_nb is not there only for hwmon/k10temp. It is a small
interface glue if you will, which exports the CPU functionality in PCI
config space to other consumers.

So it is not really a driver - it is used by drivers to talk/query CPU
settings through it.

With that said, I don't think I understand all that talk about PNP IDs
and ACPI methods. But maybe I'm missing something...

So what's up?
