WE were using the SPI on the debug connector internally at Openmoko at some
time ago to attach a SPI flash to the debug board. So the SPI on this port
(including the connection to the 2x5pin header on the debug board) clearly
works and is verified.

the debug connector FPC traces are too thin for providing power. They cannot withstand a lot of power, and we would risk frying the FPC in case of a short circuit
