You can try changing PS/2 mouse rate and resolution via the following
sysfs attributes:

	/sys/bus/serio/devices/serioX/rate
	/sys/bus/serio/devices/serioX/resolution

like this:

	echo -n "200" > /sys/bus/serio/devices/serio1/resolution

Or you could try setting both mice as separate devices in X...
