Not sure what it is.  It seems to be orthogonal to "emacs
--reverse-video", and has no effect when I try setting it manually in a
running session, nor when I run "emacs --eval='(setq inverse-video t)'
-Q -nw".

It was removed from the manual here:
b4a1a8b278 2010-03-02 Chong Yidong * frames.texi (Mouse Avoidance): Mention make-pointer-invisible.

I also found the following:

./src/ChangeLog.9:

So I have the same question as Lars: is this just some old obsolete
variable that should be removed?

Best regards,
Stefan Kangas
