IANAL either, but I don't think you're right. Since somebody has distributed
the bzImage to him, that somebody is obligated to provide him the source code
- the full source code - if he requests it. In my opinion, the .config has
to be considered part of the source code since it's needed in order to
compile the binary he received. This issue needs to be clarified.
