Ah, uhm right.  I was thinking in terms of GRUB internals rather than multiboot
on my last reply.  Sorry for the confusion :-/

If you're working on an OS kernel, just use CPUID instruction like Andrei said.
You can see our cpuid command for an example on how to do it (license terms
apply if you copy actual code).
