Whyso? I thought about that and I'm not so sure, because there are older
machines with ACPI. Incidentally, it would probably be a good idea to not
attach ACPI on older systems, based on the BIOS date like FreeBSD does.

To refine the SMBIOS idea a bit, perhaps we could skip the ISAPNP probe if:

- the machine has SMBIOS
- SMBIOS has valid entries describing expansion slots
- none of those entries describe an ISA/EISA slot
