    PowerPC kills OF because it really has to, that's one of numerous
    reasons that it started sucking the device tree into a kernel copy
    early in the bootup and using that for device discovery etc.

    To be honest, the 'ok' prompt is of limited value when you have
    things like Alt-SysRq and PPC's XMON debugger in the kernel already.

    In fact, the 'ok' prompt is an ENORMOUS pain in the ass to support
    on machines with USB keyboards, because sharing the USB host
    controller is beyond non-trivial. I've never implemented support
    for that on sparc64 and I frankly have no desire to do the work
    necessary to support that. It simply is not worth it.
