Correct, cfr. the implementation of of_machine_is_compatible().
BTW, several PPC platforms use of_device_compatible_match(of_root, ...),
but I believe of_root is not guaranteed to be set up.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
