PS4:
It's still not really nice what we do with this odd static-option-table […]
I can't speak to the original purpose, but I use it currently to offer SeaBIOS ROMs for Mini v1/v2 that always enable the EC's automatic power-on. The EC implements that, so the setting has to be written to CMOS (which is EC BRAM here) to work.
The logic change above would still work with that, with an added benefit that if the CMOS was fiddled before or during suspend, it'd be reset on resume like you said.
