I'm not sure I like this. What we do / don't find on startup is part of
the not-exactly-API. It's true that if we don't print an MMC line at
all, and we should have MMC, the user (and any scripts that parse
console output) but now we're also increasing the code size a little bit
too. I can be convinced this is a good idea, but I'm not there yet.
