YEAH!!! The Power Off INIT works great! 
It allows the standard shutdown command to toggle the PB2 line, as I needed for my soft power box -- works fine on both stock ROM and (ahem, ahem) upgraded clean ROM... thanks a BUNCH! 
The M8 is not as smooth as your M3 (I got an M2 too) but it's a great tool. You end up taking much less pictures with it than any other digicam, but better ones.
Glad you like my pics. I can always hide behind the I'm just a collector, I was only exercising the shutter cliché
Extra info on it says nothing more.
But with, ahem, a custom IIci ROM I get a slot 0 similar to yours. There is some extra info about it:
BTW, these captures were taken on the IIx, transferred via floppy to the SE/30, then emailed as attachments to the MacMini where I'm writing this, for easier (read: faster) editing
One end of the resistor is hooked at the +5 TRKL line, simulating the PFW signal. When I put the other end of the resistor in contact with the transistor base, the PSU fires up. As soon as the base is disconnected, the PSU shuts down.
At your side of the pond, you're more likely to use a 2N3904 or similar transistor, instead of the BC547 I had at hand... then your collector & emitter connections will be reversed!
That simple circuit is all that is needed for any soft-power capable vintage Macintosh to use the feature with an ATX PSU. The problem with compacts and other non-soft-power enabled Macs is that they don't generate the PFW signal, thus our hassle with the VIA, INITs etc. But as long as you manage to get a PFW signal, this very same simple transistor circuit will switch the ATX accordingly.
Now, as soon as I get some time, I'll prototype a bit on the switching box and then build it!
THANKS A LOT TO ALL!!! ;D

That makes much more sense, yes. Fortunately, the sophisticated Custom Shutdown Procedures of the Shutdown Manager came to the rescue!
Yeah, it makes a great super-wide for the M8 (16mm equiv.) On film, it's just insane }

Sure! I'm doing that on the IIx because the II is being recapped...

Sure! Both the IIsi and the ATX are soft-power capable, it's just a matter of "translating" the PFW line from the Mac to the PS_ON signal required by the PSU. A simple transistor as inverter will do. Here's my proof of concept:
