I also run Debian (Sid) with 2 video cards but each with their own monitor and mouse and keyboard and have xserver-xorg-core 2:1.7.7-2.

I have no idea whether this matters, but I use the evdev driver for the mice:

Section "InputDevice"
        Identifier  	"Mouse0"
        Driver      	"evdev"
        Option      	"Device" "/dev/input/event5" # (cat /proc/bus/input/devices)           
        Option      	"Name" "A4Tech USB Optical Mouse"
	Option      	"ZAxisMapping"  	"6 7 4 5"
 	Option      	"Buttons"       	"12"
