Here is a small patch which allows the m68060 to be used. I have not
    tested the FP switching stuff which we know is broken. This is taken
    against the libchip snapshot but should merge without problems. If you
    have any problems please let me know.

    There are other smaller issues such as superscalar enable and cache
    control which I have not addressed yet. They are different to all other
    m68k processors. These can wait IMO.
