It's a pain to attempt to auto-generate the message.  If someone is
updating flash with a CBFS file for the key, I don't think it is too
hard to also update CBFS with the desired message.  Also, if one uses
a bootsplash image, then boot-menu-message isn't seen anyway (in that
case the boot key message needs to be encoded into the bootsplash
graphics if it is desired).

FYI, the boot-menu-key / boot-menu-message files aren't new.  They
were used in the past to change to ESC on several machines.  The only
recent change is using ESC as the default.
