how to get +5V at 100mA and +6V at 2A from 7.4V or 11.1V battery supply

Hi - I need to find a way to get a low current +5VDC power supply -
probabaly always under 100ma, and a fairly high current +6VDC power
supply - normally about 600ma but I'd like it to be able to handle
peaks of up to at least 1A, preferrably 2A. 5V supply is for a
microcontroller, 6V supply is for motors. Power source will either be
two or 3 li-poly batteries in series - so either 7.4V or 11.1VDC. (I am
flexible in this - ideally I'd have a circuit that could handle either
of these voltages - but if I have to choose one or the other that is
fine as well). Efficiency is definitely key - In a perfect world this
circuit would give at least 90% efficiency - and preferrably more than
that. Also - board space is a serious concern - ideally it would take
up 2-3 square centimeters at most. I don't mind placing components on
both sides of the board.
Does anybody have any suggestions for how to do this? Thanks so much
for your time,
