I'm aware that -current kernels are supposed to support SMP
and UP without change, but we cannot use -current. We have
to use -stable. So that's not an option, I'm afraid.
I have now built an installation CD which uses the exit code
of mptable to decide whether to install an SMP or UP kernel.
It _seems_ to work on those machines on which I've tested it
so far. Can somebody confirm that a -stable SMP kernel will
boot and run on all hardware on which mptable returns 0?
