Maybe I can help.  What is the difficulty with the semantics of this
attribute of a frame?

What's wrong with this (taken from frame.c:frame-parameters) as the
frame height:

  height = (f->new_text_lines ? f->new_text_lines : FRAME_LINES (f));

and then subtract from it the height of the minibuffer window?

The C variable `minibuf_window' should give you the Lisp object that
holds the minibuffer window, and its `total_lines' attribute should
give you the height of that window.  Or am I missing something?
