Two issues with that:

1. I want to be able to boot a different kernel on reboot - this
is a development machine.

2. I believe we free all the __init stuff around the end of
start_kernel, so the initial functions and data just aren't
there any more ... of course that could be changed, but it's
both a more major change than I really want to do, and it still
doesn't solve (1) ;-)
