Some findings that might be of interest.

At first I tried using an old USB2 hub PSU which is 5V/1A and that
allows the u2 to boot and be usable but it will segv some programs when
it becomes power starved.

That seems to go away with a 3A supply, though that's above spec, it's
also nice to be able to have 1A available to make the 2x usb ports
operate in spec:

The jarcar plug is slightly off size, if anyone has the ID 0.8mm with OD
2.5mm plug tips laying around... ;)

Anyway, for core crypto operations the u2 is about 3x faster than a 2ghz
kirkwood in initial testing. This is a very nice little machine! 

I'm tinkering using the Linaro image:

Still haven't got the mail400 in the loop yet.
