I would prefer to fix this a clean way.

I would suggest to implement:

It is a more code. But it is race-free. Also it is much more clear
what is going on.
How does this sound, please?
I wasn't sure if any of the other preferred-console magic in
register_console() was needed, which is why I kept a full
register_console() call. But if it really is just about forcing it the
head and setting a new CON_CONSDEV, then your suggestion is much
simpler. Thanks.
