Touchpad tracking speed with dual monitors

I have a minor issue where the mouse pointer begins to move much faster whenever I connect a second monitor.  In this case, I'm adding a 1920x1080 HDTV to the right of a 1280x800 laptop screen.  The pointer speed seems to scale with the increased desktop space; that is, it moves much more quickly horizontally but about the same speed vertically as before.  Does anyone know how to fix this?

I use xrandr in a shell script to enable the second monitor, in particular:

xrandr --auto
xrandr --output HDMI-0 --right-of LVDS

Hardware:
Toshiba Satellite A305-S6916
ATI Radeon Mobility HD 3650 (using open source radeon driver)

Snippet from xorg.conf:

Section "Device"
	Identifier "Device0"
	Driver "radeon"
EndSection

Section "InputDevice"
	Identifier "Mouse0"
	Driver "synaptics"
	Option "MinSpeed" "1.0"
	Option "MaxSpeed" "4.0"
	Option "AccelFactor" "0.03"
	Option "TapButton1" "1"
	Option "VertEdgeScroll" "True"
	Option "HorizEdgeScroll" "True"
	Option "FastTaps" "True"
	Option "CornerCoasting" "True"
EndSection

Re: Touchpad tracking speed with dual monitors

Same problem here.

Sony Vaio E series
ATI Radeon Mobility HD 5600

Only a problem using the touchpad and dual monitors.
