What would you want it to say in addition or differently to what it
says now?

I don't see bubbles.el in any Emacs 22.x release I have here.  Maybe
you have some downstream distribution which backported the game from
Emacs 23?

I did try in Emacs 23, and I saw the same problem there.  And the
initial revision of bubbles.el I see in Git has the same problem on
TTY frames as the one I described.

Perhaps there was some bug/misfeature in current-column, which was
meanwhile fixed.

I think you want posn-actual-col-row.
