Keyboard and power management tends to be split into two on
Thinkpads, but in any case yes, those controllers generally either
have separate flash for firmware or are ASICs without firmware.

It originates from good intentions of course, "better safe than
sorry", but I think it is a bug to display it when it actually does not
apply.

Flashrom could be improved to not display some of them when they are
known not to apply, such as in your case, but there are other cases
where flashrom can't really know if the warning is needed or not.
That's more difficult.

Yep - excellent!

Maybe send a message to the SeaBIOS mailing list about that. I don't
know if that is actually expected to work. Sorry.
