Or is it with the way the new kernel is passing device info to the X-server 
and its modules?

I would try unmerging the mouse driver and only leave evdev and synaptics to 
deal with input events.  Initially try without an /etc/X11/xorg.conf and only 
the default configuration for evdev.  Then you can tweak the evdev 
configuration file to see if it starts picking up the mouse events.
