Hi Dan, that's a bit strange... I have tested the module not that long ago at all (and it's only using simple GPIO), so I'd be pretty sure it works.
Does the display show the usual solid bar of pixels? If not, it could be you're running it off 3.3v instead of VBat? Also I've found that unless I connect RW up to GND, it tends not to work.
Finally, those pins are the ones for the Espruino board. A0 is shared with BTN1 on those 2 boards and might be causing you problems - the others might be shared too. Check out your boards at the top of http://www.espruino.com/Reference to see what's free.
