The final piece of the jigsaw, in case anyone has similar problems. The Arduino IDE wouldn't talk to the Arduino board because serial.debug_rate in ~/.arduino/preferences.txt was set to 14400, a value not supported by the port (something to do with the ftdi_sio driver?).
Setting this value to 9600 cured my final problem.
