Yup. CPU is the ignorant one. Now, BIOS (or UEFI), on the other hand -
they DO know hardware. And BIOS (or UEFI) - that's sure part of x86
platform.

Sure it does, on any platform. Difference being - does kernel get
helped by PCI bus to recognize hardware (x86, sparc, possibly ppc and
ia64), or not (ARM, MIPS).

Agree.
