Your 100% certainty is misplaced.

It was only used on Quadras that required it. Other Quadras supported 
a "soft" method of performing the same function, which is what is 
used in all PowerMacs that will run NetBSD.

None of the first series of PowerMacs can run NetBSD (no 
OpenFirmware, no PCI bus, PowerPC 601 processors, all 3 of which must 
be changed to run NetBSD) and it has the same caveat as the Quadras.

The option to boot after power failure is a PRAM setting on many 
Macs. I don't know if there are OF commands to set that feature, but 
if you have the ability to boot into MacOS, you can set it using the 
Energy Saver control panel. Click the "advanced" tab, and tick the 
checkbox next to "restart automatically after a power failure" (OS9's 
Energy Saver...OS7 & 8 had slightly different wording iirc, but the 
option is still there on all machines that support it). This does 
require a good PRAM battery.
