I've changed the CPU recognition code a bit. It has grown in size,
but at least supporting new CPUs should now only mean having to extend
an array (providing that new CPUs all support the cpuid instruction,
which they should).

I'd like to get some feedback on it, especially from people running
on processors that are non-Intel. The patch is in

ftp://ftp.fwi.uva.nl/pub/comp/NetBSD/fvdl/cpuid.diff

Tell me if it works for you and correctly identifies your processor.
