Copy/pasta, right?

A better name is ediff-floating-control-frame.

I would document this slightly differently:

    If not-nil, try making the control frame be floating rather than tiled.

  If your X window manager makes the Ediff control frame a tiled one,
  set this to a non-nil value, and Emacs will try to make it floating.
  This only has effect on X displays.
