We can do that. But how does this translate into CPUID numbers? That's
all we can check.

This is a pointless statement, I hope you realize it. There are a lot
of things that should not be, but are still, for various reasons. Want
an example? A big company such as AMD shouldn't have released millions
of CPUs with broken thermal sensors. As it stands, we do what we can to
cope with their mistake.
