Timothy's original approach is appealing more and more to me. It's a
good way to know that the system will stay as it was when flashed.

Runtime setting - the argument there would be that if someone can
change the flash contents to create a new CBFS file they could also
replace the SeaBIOS payload, right?

It is sortof true, but it *is* slightly easier to write data into
erased flash than to erase existing and then write something new.
