Yeah, i know about the disableDebugPorts() issue. :)
Regarding posting in the wiki, there are two caveats regarding this board's 5V and GND busses that should be mentioned if you post this. I have no issue with you adding an entry. Luckily the Maple designers were on the ball and made sure that, except for the wonky half-space-offset on one of the Arduino headers, the rest of the pins all line up with standard 0.1" spacing. The following issues do need to be brought up though with using this prototyping shield.
1. The 5V rail is normally fed from the header block on the Mega (the two pins above pins 22 and 23). Since these two pins lie outside of the Maple's footprint, there will be no power to the 5V bus. This is actually a good thing because you can tie your choice of 3.3V, 5V, or whatever you want to this bus and it won't connect to anything on the Maple unless you wire the bus to one of the voltage pins. In my case, I am bypassing the power-selection jumper (set to External) and am applying 5V to the Vin which is also tied to the 5V Bus on the prototyping shield so that I can drive 2+ Amps from my external PSU and not from the Maple.
2. The Ground rail *IS* connected to the GND pins on the pin headers, however the GND rail is positioned directly above the unpopulated pins 21 and 22 on the Maple. If you have soldered a pin or socket header to pins 21 and 22 on the Maple, you will not be able to directly extend them up to this prototyping board.
