How about specifying the NetBSD-only external disk as the startup disk? That
should mean that the Mac will be forced to wait until the disk spins up
before booting; it will then find out there is no Mac OS system on that disk
and revert to trying to boot from the internal HD.

Sounds plausible...

Well, I've read the other responses.  I don't know of any way to make the
external drive respond faster, or to make the Mac boot slower, but you can
of course make it look for the external drive by specifying that in the
Startup Disk control panel.  All I've got to add is that there are some
neat power control devices (basically programmable power stripts)
available from Sophisticated Circuits (http://www.sophisticated.com/) for
managing power.

Although the control software is MacOS-based, the device itself can store
programming, and can do things like apply power in order, with delay, to
the different outlet groups.  I believe that you can program it to
automatically do this after a power failure, but I haven't done it. The
telephone-line surge-supression sockets also allow you to control power
outlet groups with a phone call.  Although I have one (the model 200),
it's not connected to my NetBSD machine, since I've got all three hard
drives mounted internally, and my other gear needs it more.  I use it to
make sure that my Zip drive and modem etc. get powered down automatically
when I shut down my PPC MacOS machine, and powered up when I startup.
