For booting preferences I have the following items checked:
        Extra debugging info
        Don't disable VBL interrupts on video cards
        Don't bug me about untested machine.
        Auto-size RAM
        Kernel Location: NetBSD/mac

And once it gets to:
        ae0 at nubus0:...

The machine just hangs.  I also tried it without "Don't disable VBL..."
checked and it hung then too.
