    Okay, we can ignore bit 13 (the '2') since that just signals to the
    parport layer that we want address rather than data, and bit 6 (the
    '4') means EPP. 'rejected by' means that peripheral knows that the
    host wants to talk EPP, but it can't (as opposed to just being
    confused by the negotiation), and the host should choose another mode.

    It definitely speaks EPP rather than ECP? Also, what happens if you
    just fool parport_negotiate into thinking that the peripheral is happy
    (i.e. set xflag to 1 before the 'mode && !xflag' test)?
