[PD] Synaptics touchpad input not working

The problems I now have are that my version of xinput is 1.3.0 (Ubuntu 
Hardy) and I don't have the --set-prop option. Since the GrabEventDevice 
option in xorg.conf messes up my xserver, I tried removing the synaptics 
driver completely and I can now get the data in via [hid] and 
[linuxevent]. The problem is that I no longer have two-fingered 
scrolling and can't disable the touchpad tap without a driver. I tried 
to install the Alps driver but had an error as reported here:

any help appreciated
