What you want is for one input device to be a core pointer, and for the other to 
send core events.  This is something that should get into bugzilla to change how 
a config is setup for more than one input device when system-config-display runs.

Section "ServerLayout"
         Identifier     "Layout0"
         Screen      0  "Screen0" 0 0
         InputDevice    "Keyboard[0]" "CoreKeyboard"
         InputDevice    "Mouse[2]" "CorePointer"
         InputDevice    "Mouse[1]" "SendCoreEvents"
EndSection

As I've understood from docs, they will compete for being the corepointer 
otherwise, probably leading to what you're seeing.  The alwayscore is probably 
forcing the mouse to not report events.
