As far as I know, mouse movement by Emacs has never worked in OS X.
The following change to frame_set_mouse_pixel_position allows you to
move the mouse from Lisp:

(test with (set-mouse-position (selected-frame) 0 0))
Still some things to fix:
With a portrait monitor to the left of the main monitor (the left
monitor being in the negative x-coord. space), running the above test
code on a single frame inside the left monitor leaves the mouse pointer
about half a frame further down than the bottom-left corner of the
frame. The pointer should end up in the top-left corner.
Also, tested only in 10.6, but it should work in later versions.
