I'm starting to make the final modifications to the board that will become Rev C. All the modifications are minor but they sure will provide a good overall board with all your great inputs. I have taken a good range of suggestions from this thread and after talking to the fab house they are good with the mods:
- diode for the 7805 so that it doesn't work that much when not supplied at 12V.
- 2 rows of pins on the Z axis.
- an additional freewheel diode to the hotend FET.
The board already has it's entry in the RepRap's wiki:

With firmware upgrade instructions, configuration, ...
I hope you like it.
Thank you all for your contributions. It is making this board one of the best entry level electronics out there: simply connect and print. No need for heat sinks on FETs or FET replacements, great native USB transfer speed of gcode files to onboard microSD card for autonomous printing.
Any LCD/keyboard designed for the sanguinololu or teensylu will just work with the board.
