Rolled back to 14.3 and saw a few differences:

1) 15.0 creates 4 input devices: event6 to event9, where 14.3 creates 
two devices: event 6 and event 7.

2) 14.3 moused uses /dev/ums0 not /dev/input/event7

3) 14.3 moused uses "-t auto" for both touchpad and USB mouse, where 
15.0 moused uses -t evdev for USB mouse, and no-type for touchpad.

Will stay with 14.3 for a while then test 15.1-BETA / RC later.
