I think we can conclude from this that we've located the I/O ASIC on my
board.  I think it's curious that the PC has a 4230, which is asic rev 3.
I have an older I/O ASIC with no R4230 or similar part designation, which
identifies itself as asic rev *2*.  Clearly, we're going to need to track
down the tech specs of my L1A7385 asic if we're going to get anywhere with
the SC.
