I don't know.  And I don't know if that would work, it would require
investigation.

Emacs already writes to the bottom-right corner in case neither "am" nor
"xn" are defined for the terminal in question.  vt100 and xterm, for
instance, have "am" defined here, so Emacs doesn't write to the
bottom-right corner.
