The mouse seems to get detected perfectly and this is the GENERIC kernel 
build that has the modules.  The mouse gets detected and listed at boot 
time.  However, I don't think I am getting data out of the mouse port.

I beleive in the past I have checked with

#cat /dev/ums0

and if things are working corectly, cat display binary garbage on the 
screen when you wiggle the mouse.  Try this after killing moused (moused 
makes ums0 unavailable).
