On the Sumo11, I sacrificed the second two PWM ports to create the
servo ports. There is a detailed chart of how the ports are broken up
in the Expansion board docs on the www.1sorc.com website. You should
be able to use that along with the Handyboard drivers to regain those
two PWM channels, but you will have to sacrifice the servo ports and
digital out 8, which is exactly what the Handyboard does.
Here's a direct link to that chart:
