Good list!. Of interest there is a FitPC3. http://www.fit-pc.com/web/introduction-to-fit-pc3/ It has a low power budget and rich I/O resources. Perhaps if someone would contact them and invite them to the party they could close or help others close the gaps. It has promise.
I especially like the input power specifications of the FitPC for the OLPC context. The panda board (ARM) is interesting. It lacks a disk port (SATA) although USB disks work. The power requirements are nice and low but require external regulation (more than the FitPC if I read the specs. correctly. It lacks a case... some assembly required. While OK for me I doubt it will fly based on the email traffic I have seen.
