I'm not sure about the Mandrake kernels.  However if you ask a kernel
developer, they'll tell you that a vanilla SMP kernel will run fine on a UP
box, you will just loose some performance because of extra locking.

My guess is that many of the patches are not SMP / UP clean.

There is no silver bullet.  Plus, werewolves make better neighbors than
zombies, and they tend to keep the vampire population down.
