kconfig allready allow you to override values simply by appending to
the end of the .config file.
So it is a matter of creating the proper stuff around to:
1) use it
2) make is simple to update defconfigs
A simple extract delta between two config
I'm not up to do that at the moment - but it is doable.
And I would hate to see the defconfig disappear just because
they are so visible in Linus' dirstat.
