Well, it can be for various reasons. For example, the interrupt tree
cannot be properly parsed, we don't get the OF "phandles" and we now
rely on them (MacOS don't keep them when it gets the device-tree).
Also, some bus mastering devices aren't properly shut down, potentially
screwing things up in memory while the kernel loads.
I would really recommend you give a try to yaboot before investigating
(Note: I do have a sawtooth here which just works with latest kernels)
