I've tried that for one evening without immediate results, then got
distracted again.  My basic idea was to compile a kernel, measure the
size, apply a patch, recompile and measure the new size.  One could even
do something similar to git-bisect that way, each time ignoring the half
that causes less bloat.

The main disadvantage I see is with the overwhelming number of new
config options being added.  Going from 2.6.x to 2.6.x+1 will add so
many new options that I usually just 'yes "" | make oldconfig'.

If someone can translate my description into a few lines of bash or
perl, we could turn it into a "make bloatcheck" and require^W hope that
at least some people use it, get ashamed and fix their mess before it
even hits the list.
