I *think* this can be prevented by setting an Open Firmware password
on newer machines which support the feature.

This will prevent

- Single user boot
- Verbose boot
- Hitting the Alt key to select a different boot volume

and probably other stuff...

I'm not sure if they fixed that password bypass thing
by changing the amount of RAM, though. But at least
you have to open up the machine to do this.
