I highly suspect that it is not.  However, I think certain sections of the code
could be shared, or perhaps we could just provide all the files in one place,
and each port picks and chooses which are common, and supplies thier own for
the others?

Sorta.  I'm playing with the one on prep right now, which is a CS4232.  I have
the DAC working, and can play audio files, and they run the dma engine, and
take the appropriate amount of time, but no sound at all.  I suspect something
in the various mutes, outputs, etc.

Supposedly on the pegasos, it panics.  On the rs/6000, there are more serious
issues, as the rs6000 responds differently to certain commands, like nextprop,
and will loop over the properties again.  Basically, firmware wierdness.
