	While I haven't done even an eyeball check recently, not too
long ago the size savings for an aggressively pruned kernel could be
quite noticable; there was also anecdotal support (waves hand)
forfaster performance.
	Barring that?  Every part of the kernel is something that can
possbily go wrong, either by itself or by interacting with another
part; if it isn't there, it can't break.  Now the record on this
really pretty awesome ... on the other hand, I can't argue with the
person who doesn't want to roll those dice.
	And compile times of current generation hardware are pretty
short.  On an AMD Phenom II x4 940 (3 ghz) it's 5 minutes, maybe
less.
