And here's a tested version. Curiouser and curiouser. I think the mapping
of ACPI tables to sysfs nodes still needs a bunch of work...

========== CUT HERE
Handle PNP devices that have the same IDs a bit more sanely ... this at least
arranges multiple one-to-one mappings between PNP nodes and ACPI nodes that
all share the same PNP0c02 id. (Maybe mapped to the wrong node though...)
This remains a hack, since it masks failures where PNP0a03 (a PCI root bridge)
is handled by ACPI special case code (/sys/devices/pci0000:00 on my systems
instead of /sys/devices/pnp0/pnp00:0/pci0000:00!) not pure PNPACPI logic.
I suspect that pnp_dev.number and some acpi_device field need to be compared,
(so the right PNP0c02 nodes hook up to each other, PNP0a03 likewise) but I'll
leave that to someone who knows how those ACPI table lookups "should" work.
