    I've read through this pdf. As far as I can find, it just talks about
    how to setup the base address for each of the sets of registers
    without actually talking about the sets of registers themselves. Nor
    can I find in the document a pointer to the different register sets.
    Do you have one of those as well? It looks fairly easy to program
    this device's base addresses or inquire what they are. It is done in
    much the same way that super I/O chips are programmed.
