I made a mistake there.  It should of course by `make-local-variable'.

Yes, I thought as much.  It might work if these buffers are dedicated or
never displayed in two frames at once, but still requires hackery.

I found a lengthy discussion in emacs-devel, which started with a bug
and apparently concluded with the realization that nobody needs
frame-local variables.  Sorry.  I think there is no other way to achieve
what you want.

I had no success with `make-variable-frame-local', either, though it should
theoretically work.

`modify-frame-parameters' won't work, because there is no
frame-parameter for this.  I find the documentation a little fuzzy on this.
