Hello.

Thank you very much for the hint. Doing like suggested make me feel
back in the times of "config" for BSD kernel configurations ;-)

Well, as I stated in the original question, the subject is a littel
project where we'd like to compile those modules into the kernel. That
is a requirement given by higher order (no modules available,
everything needed needs to be static in the kernel, no
loading/unloading of modules allowed for security purposes).
