Indeed. Have you looked at the Wiki page on the effort?
http://wiki.laptop.org/go/Marvell_microkernel and sign yourself up.
Can you answer any of the questions there?

Are you on the OLPC devel mailing list? You can sign up at

I can introduce you to other people working on Open Source Hardware if you like.
