Panda board has very nice specs.

The FreedomBox project is looking for very cheap hardware. This hardware
exists today, but it is used for running Android. It would be very nice
if we could liberate this hardware and use it for our own computing.
Beagle board and Panda board are very nice but i don't think they will
become cheap enough for the FreedomBox (one monopolistic manufacturer,
low volume - "only" 8900 Panda boards sold)
If the FreedomBox would use a popular SoC then the manufacturer of the
motherboard seems less important to me. All the major functionalities
for which drivers are needed are on one chip. We could simply switch to
an other board with the same SoC and still run our software (maybe with
some minor adjustments, please correct me if i am wrong...)

You find out the manufacturer of the motherboard inside a tablet. Then
you contact this manufacturer and say: Hi, i know you are making 10000
motherboards for Yarvik, if i were to order 1000 of these boards what
would the price be? I think the manufacturer will be happy with an extra
order. Mass produced boards are well tested (the manufacturer simply
can't afford mass problems) and cheap.

Not quite true i think, especially for SoC. My FreedomBox has an Marvell
6281 (Kirkwood) SoC inside. This chip has been around for a long time.
You are right for non-SoC boards, they can more easily change for
example the graphics chip and spoil our fun.
