you funny man.  :-P  actually, it wouldn't help since all of those
laptops have 64-bit AMD CPUs so PAE doesn't come into play.

the actual issue is that, if i have a 32-bit, PAE-enabled system with
<4G of RAM, obviously, PAE won't be relevant and i'll get a regular
kernel installed.  but what if, even though there's <4G *now*, i know
that i'll be putting in several gig next week, so i'll want the PAE
kernel in preparation for that?  better yet, does it hurt to have a
PAE kernel even if you don't need the PAE functionality?

good point.  i'll wait a bit to see if an answer pops up here and, if
not, i'll try over there.
