    Hi!

    Compaq Evo notebooks seem to use non-standard keycodes for their extra
    keys. I workaround that quirk with dmi hook.

    I think that number of such workarounds neccessary should be
    reasonably small (like one for each manufacturer), and therefore this
    would be good thing...
