Thanks for this.  Unfortunately, connecting a standard ps/2 mouse (which
requires 5V) isn't really an option on the BTest boards (upon which the
ps/2 ports run at 3.3V).

Just out of curiousity, I booted into OFW and did a "select /mouse".  It
hung (no "ok" prompt, no further input accepted).  I had the old
revision of the touchpad hooked up to the ps/2 port on the BTest board.
