Note that the RJ45 connector is not just a socket.  It includes
the isolation transformers, according to this datasheet:
http://www.haloelectronics.com/pdf/fastjack-10-100-tx.pdf
So be sure to reuse it (and not a plain socket) on your main board.

The good news is that this device has VCC on pin 4 and GND on pin 8,
which might solve your other problem of injecting 3.3 V into the netCF
(assuming the regulator doesn't mind 3.3 V appearing on its output).
