This is new functionality that I think should be separate from this series.

This feels like something that should be machine readable and verifiable
rather than a human readable string.

That's not to say a freeform record for human readable information
wouldn't be useful, but I don't think it should be restricted to just
the CPU name.

7 bit ASCII is rather quaint.  Would utf-8 be better?
