Well the rewrite for new apis would happen first, then the code can be
merged into the staging tree, then we can do the "real" cleanup
afterward, with everyone helping out.

I think you need to lay out exactly what you want/need done here, as it
sounds like both a lot of different things, and pretty vague.
Do you want to go through the above tree and look at the diff and pick
the different pieces out, or do you want me to do that and ask you about
all of them?
Also, how can I get a sample device to test that I don't break anything?
