NetBSD does not call the quiesce method. I'm wondering if this is why
we have so many problems on the new world Macs.

Unfortunately, fixing this won't be trivial, because we currently use
OF all the way through autoconfiguration, and even after booting to do
frame buffer stuff. So this will take some major restructuring.
(First, sucking the device tree into memory at startup like LinuxPPC
and Darwin do, and second, driving the frame buffer directly rather
than through OF.)
