Those are just plain wrong; please fix up the intel-family.h thing like
suggested earlier in this thread.

And Tony, please no more of that platform name nonsense.. we want uarch
names for a reason, so that enums like the above become something
sensible like:

	case INTEL_FAM6_ATOM_CRESTMONT:
	case INTEL_FAM6_ATOM_CRESTMONT_X:

and now it's super obvious why they're grouped.
