>Description:
        After installing NetBSD on a Mac Mini G4 1.2GHz, the system can
        boot correctly iff I manually drop into the OF prompt first and
        type "boot" from there.
        
        The auto-boot functionality does not work correctly: it seems as
        if the kernel starts but it fails to initialize the screen.  The
        screen remains blank and the system is unresponsive.

        Defining the following in OF lets auto-boot work, but this workaround
        should not be necessary (it's not for Linux):

        boot-command=." hello" cr " screen" output boot

        Please note that the fact that the screen remains blank may be
        unrelated to this problem.  It is possible that the problem happens
        much earlier in the kernel boot process, but I can't debug this.

        I'm attaching the kernel log below after the Fix section.
>How-To-Repeat:
        1) Install NetBSD onto the hard disk of a Mac Mini G4.
        2) Set the following OF properties (or similar):
           boot-device=hd:,\ofwboot.xcf
           boot-file=netbsd
        3) Type 'reset-all' and drop into the OF prompt again.
        4) Type 'boot' and see that the system boots fine.
        5) Reboot and let auto-boot start NetBSD.
        6) See a white screen and an unresponsive machine.

        7) ... define the boot-command mentioned above and see how auto-boot
           starts working.
>Fix:
        Unknown.
