Well, you may now find that it's not any easier going the other
direction. If you have to put significant effort into either a forward
port of the board code, or a backport of crypto and/or 82xx
arch/powerpc support, it's more useful long-term to get yourself
unstuck from the old kernel -- and people will be more interested in

You can try it, but you're on your own. That was a very early attempt
at support for 82xx in arch/powerpc. I do not recommend using it at
all, much less sinking extensive backporting work into it. Things
change for a reason.
