Well, what Kay said was "it should be on *every* system", making it sound like
it's an option past its shelf life.  Certainly, "the default should be null for
the vast majority of systems" is a different scenario.

Hmm.. I suspect diffconfig will only get me part of the way there.  Maybe what
I *need* to do is find a 2.6.25-ish x86_64 defconfig, the current one, diff those, and
then see what changed (as opposed to truly new config flags), and then see
how many of those changes do/don't show up in *my* config as well..

Maybe that would be a good project for some #kernelnewbie to look at ;)
"In my copious free time" ;)
