No problem, as I said, I want to use the same *sources*, not to be able
to hot-swap the scheduler. But basically I have a directory named "configs"
in which all of my machines configs are stored. I run "build-kernel-list"
over those configs from the kernel dir and I get all of my new kernels.
You can now easily understand why I don't want to patch in the middle of
the process :-)

Thanks,
Willy
