Actually, the reason I thought it had to be preloaded was because of
confusion with some prior similar cases.  The only drawback of not
preloading it is that we need to duplicate the same code in the
defcustom and in startup.el and make sure that the two stay exactly in
sync.  But that is not too bad.  The following patches enable tooltip
mode at startup while taking care of the Custom problem.  The patch to
startup.el merely adds a comment.

I can install if desired.

xterm-mouse-mode could be taken care of in a similar fashion (without
preloading) if that would be what we want to do.
