Not really.  I'd imagine you already make a copy of OF for internal use
based on the tree, which is located at a static location.  The only issue
would be passing in a pointer to the location of the custom tree instead
of using the "real" one that isn't there.  Just put the temporary data
right after the kernel along with whatever boot parameters you pass in.

Define "talking to".  Do you mean reading from the tree or actually doing
OF calls like for OF-based drivers?
