module-rebuild shouldn't really have this task. it isn't the right place
to do it. It will of course quite happily do what you need it to do,
rebuild anything which installs a kernel module from portage.

I don't particular feel comfortable doing this. the only place I can
actually see this being of some use is with the pkg_config since an
ebuild postinst is far too soon, and patching up Kbuild to do this is
far too intrusive (let alone high maintenance).

A possibility (although I wouldnt like to promote it through portage)
would be to have a wrapper/helper script which would do all of this for
you. build-kernel or some such. But then... whats genkernel for right?
