Can you use this to abstract real OF too? We don't support real mode 
Open Firmware and IBM is shipping new systems with a very basic firmware 
that runs only in real mode (this includes the Bimini 970MP dev board, 
apparently, as well as their Cell blades). The easiest course seems to 
be just to pretend it's a flattened device tree if we can support that.
