I think we'll need such a tree walker anyway sooner or later.  Thus 
you'll get bonus points for making it generic, so it could be used for a 
-- say -- late_init() callback too.

Also the reset() callbacks order will be based on the position of the 
device in the tree instead of being more or less random.

cheers,
