I'm a little confused.  CONFIG_OF_FLAT_TREE is needed to boot any powerpc kernel.  Are you 
saying that the two options are mutually exclusive?  Shouldn't CONFIG_OF_LIBFDT be a 
subset (instead of an alternative) to CONFIG_OF_FLAT_TREE?  That is, you need to define 
CONFIG_OF_FLAT_TREE in order for CONFIG_OF_LIBFDT to be recognized?

Maybe I should have been paying more attention to your libfdt work, but I was assuming you 
were just going to alter the back-end handling of OF trees, not break existing code.
