I have worked much with a sister-product to this board, mostly administration of a new Linux system and developing in CGI-C on it.  There should be a default busybox install on it from the factory.   I could come in early so we could slap something together, making sure I can boot the board, minicom in, and maaaaybe make sure a cross-compiler works from my laptop (it's an iBook G4!), tonight.

At least I could bring that to the table, if that's at all practical.  If I know by today's end that this could be used I'll at least see if I can boot and minicom into it tonight.
