Hi - I am designing this circuit board at the moment, through contact
with Aleph1. It will probably be based on a couple of Maxim regulators,
as on the Balloon itsself, and a Maxim LED backlight drive.

I haven't got a prototype to play with yet, but when I do - I'll attempt
to get the kernel framebuffer console to work on it.

I haven't looked at the kernel side of things yet, and am no kernel
expert, so don't ask anything too technical of me in this regard.
