It could be possible that the M961_MP_MB board uses a separate mini lan board to convert a 8 pin standard ethernet connector to a 6 pin connection for the board.
At this point I am just not sure.
However, I did find out that this board was used in the PCG 61212T model family of SONY vaio.
So if anyone with that model could confirm this or if any sony tech expert could help me trace the part number then that would GREATLY help me.
