That's what I thought too, when I first heard of this problem.  But if
you go look at swfree(), in vm/vm_swap.c, you'll see that it explicitly
makes sure that it doesn't "use the first cluster of the device in case
it starts with a label or boot block".  Now mind you, this code may be
broken somehow - tho it looks about right to me - but it's certainly
not as simple as just swapping over the disk label.
