We could still have some sort of nexus node that is off to the side 
(pointed to with sleep-parent) and not inserting itself into the hierarchy.

Or, we could allow multiple nodes to refer to the same sleep ID, and use 
the ID rather than a node to tie things together.  If we do that, we'll 
probably want a simple index rather than a set of bits in the sleep 
property, so it can correspond to some kernel object that has some 
bookeeping info.  Perhaps we could tie into the clock bindings that were 
discussed on devtree-discuss in August.
