I think this is a good solution for you. It's a little confusing to
find were this work is but you can look in the linux-yocto kernel tree
- then the actual cfg fragment stuff on different branches.

http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-3.0/

meta branch contains meta/ which contains a lot of the cfg fragments,
and patches, etc. There is also a document in the git repo as well
which is worth a look.
