Graynomad,
I re-read the latest schematic. J1 in the schematic is pins D8-13, J3 is pins 0-7. SS is marked on J1-3, which is pin 10. This is for the ethernet controller. PD2-, an interrupt, is marked at J3-3, which is pin 2 (hopefully the jumper is not connected). SD-CS is marked at J3-5, which is pin 4.
Could you re-check? I'm trying to design a shield compatible with the ethernet shield, which I don't have.
