    Behavior is slightly different with a UP kernel. Neither encoder
    receives more cpu than X, but they each still receive more than gforce.
    The distribution of X/Gforce vs lame/lame averages per eyeball to
    roughly ~50:50.

    I noticed Con posted an accounting fix, and applied it. No change.
