Yes, but you don't build the machine based on the device tree.  What 
would be useful would be to be able to simply write a device tree 
description and that would fully represent the board such that you 
didn't need a ppc440_bamboo.c file at all.

So what I'm getting at is, what is preventing us from being able to do 
this today?
