Let's be clear:

1) Ubuntu currently ships and supports separate packages for UP and SMP

2) Ubuntu is experimenting with (in the developer branch) a patch that will
 dynamically optimise out the SMP locks on UP systems, thus allowing us
 to build only one kernel package for both UP and SMP systems
