Sounds like you want to adjust the RightEdge Coordinates. Try tweaking
Option "RightEdge" "integer"

Take a look at the synaptics man page (where you'll find a diagram
showing how the touchpad is split up).

How you make this change will vary depending on what versions of the
xserver and synaptics driver you have. You'll either have to do the
SHM/fdi file hack or you'll be able to set this through the xinput
utility.
