That does nothing, but the following resizes the frame:

(modify-frame-parameters nil '((left . 0) (top . 0) (width . 100) (height . 48)))

And has done the right thing:

(frame-parameter nil 'height) => 48
(frame-parameter nil 'width) => 100

Bad:

(frame-pixel-width) => 1849
(frame-pixel-height) => 1680

Good:

(frame-pixel-width) => 1849
(frame-pixel-height) => 1680

--with-x-toolkit={none,lucid} both work fine (although you can see the
  modeline of the frame appear as if it were 80x36, and then it
  resizes correctly to 130x56).
