May I draw your attention to the Hackerbus white paper ?
http://neo900.org/stuff/papers/hb.pdf

There are enough GPIOs for 1 bit operation, or if you use some of the UART signals as GPIOs, then there are enough signals for regular 4 bit operation.

The regulated supply voltage available on Hackerbus will probably be 2.7 V, which is just at the lower end of the standard SD card voltage range.

Finding a nice place for the card holder would be more of a challenge. I guess there should be sufficient room if you remove the camera. Else, some creativity may be needed :-) When looking for such a place, the scans and photos here may help:
