Ah, right. Thanks for tracking that down. I forgot to factor out
isapnp_to_pnpid() and pnpid32_to_pnpid() (and acpi_ex_eisa_id_to_string()
for that matter, though that's buried in the ACPI CA)-- they're really
doing the same thing and we should only need one copy (plus the CA
one).

I'll wait for another round then, before reviewing this further.

There's actually a hex_asc() helper in kernel.h, so before you overlook it as well, this is a somewhat nicer ID fix.
