Not sure why the BIOS wont save your choice, it saves it here in mine :)

We include the xf86-input-synaptics-1.5.0 out of box, but the ksynaptics
package is very out of date, for KDE3 and probably doesn't even work
anymore. There is x11/gsynaptics/ in ports, but I don't know how well it
works. You want to give it a shot and let us know?
