Added these details in http://wiki.debian.org/DreamPlugTesting (they're
more about the HW than about FreedomBox, so preferred to add to that one
page).

OK, many thanks.

I've added these details to
http://wiki.debian.org/FreedomBox/DreamPlug/Images this time.

... together with a bunch of wiki "gardening", which I hope won't break

Many thanks for your response.
