I'd like to suggest you check out the "tweaks" idea I tossed out here:
http://www.ussg.iu.edu/hypermail/linux/kernel/0211.0/2229.html
If this sounds interesting, I've got a version of the patch (albeit old
and not applying directly right now I bet) that moved things into header
files and got all of the dependancy stuff correct except for the initial
run (so I think I was forcing an update with any make invocation, but
there were no spurious recompiles).
