Hi

I have a really crude serial console setup in place now, but very little
time, and even less experience with u-boot. I should be able to do the
tests for you on Saturday night (UTC+2). Perhaps over IRC might be a
good idea, in case I need some hand-holding, and if you still need the
help by then.
