Got this information from Peter, as he notes below.  I'm just the messenger
on this particular change; I'm merely trying to upstream
the information he provided me.  Whatever you folks want, I'll be happy to
do.

Ok, fine.  Seemed trivial enough and didn't seem like the code churn for
another patch was warranted.
But, ok.

This is part of the change for the hardware revision, and it seems pretty
clear that they're related to me.  The text of the two output messages are
now more aligned, and they are both related to reporting the hardware
revision.
