    Problem: every bloody line will go through the parser. There is too many
    lines. Compilation is realy slow today. I'm affraid this approach would
    make it worse. Note that 2.4.0-test7 has more than 2.75 milion lines.
    Or did you mean drivers will be (optionally?) excluded from this

    I can understand advantages the if(CONFIG_FOO) approach has, but I'm not
    sure it is worth compilation slowdown.
