I thought that perhaps the socket could also be for an Intel or Zilog peripheral chip. However, I wasn't able to find one that matched the pins you listed above. The board in Dave Dunfield's photo also has the same empty socket. It could be for a proprietary expansion. This is also a little strange. I would think that any expansion would use headers like the others on the board rather than a socket.
