Please help me to understand your answer: You are saying that I do have
to change the machine or distro config used for ALL recipes, to be able
to use a different kernel configuration in ONE recipe, right?

I was really trying to avoid that. :-(

So it is really not possible to just select a different kernel config
within a normal recipe without changing the global configuration?
