Yes, but if SMP for Athlons is not supported, what is the point in
allowing CONFIG_SMP + CONFIG_MK7 (or CONFIG_SMP + CONFIG_MK6)? Such a
kernel will not run on *any* SMP system, since AMD kernels do not work
on Intel. If an AMD user really wants to carry around SMP baggage for
no reason, let him use CONFIG_M586TSC.

This is like offering MCA-bus drivers for 'make config' on SPARC.
Sure, they might compile, but nobody will have any use for them. Thus,
we ensure that they never appear on the menus in the first place.
