This is about ready to go live. The question is how do we do
this. There is a danger there are bugs left which could brick
boards. ie destroy the bootloader and if you don't have jtag there is
no way to recover the hardware.

There are a few options:

I commit it and let people test it. If there are major problems we
undo the change while we debug the problem.

I put the code on a branch so that a few people can test it and so we
get a better idea how stable the code is with hardware i don't have
access to.

I can send patches to people who would like to test.

Suggestions welcome.
