Well, I'm getting back to my original feature request.  That is to allow 
the
Option/Alt key to be Meta rather than the Unicode key (or whatever you call
it) and leave the Apple/Command alone for the traditional Mac purposes. 
This distribution doesn't need the smoke and mirrors that Aquamacs employs
to accomplish that.

2-finger scrolling is like mouse wheel scrolling.  Dragging 1 finger on the
tracker pad moves the pointer, 2 fingers scrolls.  However, I have 
discovered
the problem is not with the API, it is just that mwheel support is not 
loaded
currently by default.  The following snippet does the trick:

;; Enable wheelmouse support by default
(require 'mwheel)

;;Define the mouse scroll wheel
(defun up-slightly () (interactive) (scroll-up 5))
(defun down-slightly () (interactive) (scroll-down 5))
(global-set-key [mouse-4] 'down-slightly)
(global-set-key [mouse-5] 'up-slightly)

;;Support for scrolling Griffin powermate
(global-set-key [wheel-down] 'up-slightly)
(global-set-key [wheel-up] 'down-slightly)
(global-set-key [double-wheel-down] 'up-slightly)
(global-set-key [double-wheel-up] 'down-slightly)
(global-set-key [triple-wheel-down] 'up-slightly)
(global-set-key [triple-wheel-up] 'down-slightly)
