I remember taking several tries to get it going initially, but now I can't 
work out why I had trouble.

Press Aux and hold
Press Power and hold
Hear tick from speaker
See red light flash on Aux
See uBoot screen
Release buttons

Timing doesn't appear to be much of an issue so long as the Aux button is down 
when the power button is pressed. From pressing Power to uBoot screen is 
between 1 and 2 seconds.
