I have one of these 3G dongles, it should work from Freerunner battery
OK since we have a charge pump for the full 500mA it is allowed to pull.
~ It certainly works out OK for USB memory sticks anyway.  "Battery life
will be impacted" it is fair to say though.

If we have pppd in the rootfs I will give it a spin later, since I got
it working on my laptop using pppd and magic dialler / expect type scripts.
