I know nothing about that and have never had to do such a thing
historically. I've never had to identify "4.8.7f1 devices".

Turn the PowerMac on with the SSD already plugged onto the
IDE adapter that I have in place. (The G3 is configured
such that I also have to type mac-boot to OpenFirmware.)

It is the same SSD being moved between the 2 dual-core socket G5,
2 socket G4, 1 socket G4, and the G3. So it is significant that
the 2 socket G4/G5 do get to the loader prompt but the others
do not.

1-socket G4/G3 example lines:

   Boot loader: /boot/loader
   Boot volume:   /pci@f2000000/mac-io@17/ata-4@1f000/@0:3
END QUOTE

No more shows up for the 1 socket PowerMacs.

SSD hanging off the IDE bus via an adapter.

It does not. See above.
