It's kind of hard to do too much of this, though, until ARM kernels
can be relocated.  They mostly all live at different base addresses
(and 8960 might also move).  Throw CPU differences into the mix and it
gets messier.

I'm not saying it isn't solvable, but there are a lot of things that
need to be done to get there.
