George,
Agreed about it being silly for swap on a *nix box, but if you're running on a brain-dead OS that is going to page stuff out uncontrollably (NT/W2K) even with lots of available memory - its still a good idea to give the OS some pagefile space on NVRAM.
I should have called it pagefile - not swap.
