Right - that's an old driver. I'm using dapper. Note the change from
xorg-driver-synaptics to xserver-xorg-input-synaptics.  

I haven't configured anything in ksynaptics, just used the defaults, but
without ksynaptics installed, my touchpad acceleration was much too slow.

Here's the important stuff in xorg.conf - it may not be optimal, but I just
took it straight from the README.alps settings:
