That's what I couldn't figure out from the i440FX spec, but I believe
one could argue that "reset" should in fact re-set the state that was
observable at VM startup.

I'm either not looking, or not admitting it! :)
In earnest: I "approached" Platform Initialization S3 resume cautiously,
then fled in a panic. See Chapter 8 in Volume 5 -- Jordan convinced me
that this scripting language was in fact reasonable, but the work needed
to follow through OVMF PI, make it S3 resume compliant, and record
everything into a script at cold boot looks very threatening.
Regarding S3 in SeaBIOS CSM: I haven't tried it yet, but I can press the
button in guests if you want me to.
