"unrecognized" in the sense that it is not on the whitelist above. It
contains only one MSR and when the patches for the interface to that MSR
get upstreamed, it won't be needed anymore.

But this all is WIP anyway so we'll adjust that printk when we know
whether we wanna have a whitelist at all...

That's spreading out the statements for better readability. That file
could use more spreading out too.
