Yes, then that member you're adding should not just be called "cpu_type" but
either "vendor_cpu_type" or "hw_cpu_type" or whatnot and every vendor can then
put its own values there.

And for the future we could do functions which convert from a vendor CPU type
to a generic one. If we ever decide that we need the generic ones.

Thx.
