You may want to check the {Top,Right,Bottom,Left}Edge parameters as well
as the TapButton[123] parameters.
I'm still trying to figure out what but the *Edge parameters seems a
little bit broken right now (or my configuration is).
Try to use synclient for that:
- "synclient -l" to see the current configuration
- "synlient param=value" to set an option

I have this in /etc/hal/fdi/policy/

<match key="info.capabilities" contains="input.touchpad">
	<merge key="input.x11_driver" type="string">synaptics</merge>
	<merge key="input.x11_options.CircularScrolling" type="string">true</merge>
