I think this is too much of a PC PoV. ACPI is designed to bridge
the gap between legacy machines and legacy-free machines, but it
is not a thingy to enumerate ISA devices. Processors, APICs and
the likes are all present in the ACPI namespace and definitely
are not ISA devices. I like to think that ACPI allows enumeration
of devices that are not attached to a bus and in that way serves
as a bus itself.
