    ok, i see the flaw in my logic. the Kconfig variable 405EX isn't
    tested *directly* by anyone, it's simply used to further "select"
    other variables, which my script doesn't take into account.

    config 405EX
    bool
    select IBM_NEW_EMAC_EMAC4
    select IBM_NEW_EMAC_RGMII

    i don't think i'm quite ready to add that logic to a simple scanning
    script.

    oh, well.
