That works for me, just need to wrap my head around where / how all
the CPU detection information is split up in the kernel since I see
some of it happens in the boot loader and some in the actual kernel.
Not sure yet if anything extra will be necessary to pick up the
topology data, though I was under the impression at least some of that
required ACPI.
