Hi Jason,
Thank you very much for your prompt and helpful reply ! The method on the page you pointed worked fine.
What I did was following.
I went to http://w1.894.telia.com/~u89404340/touchpad/index.html and downloaded the latest synaptics module for XF86/X.org, i.e. synaptics-0.13.2.tar.bz2 .
Then I extracted it and did
make; sudo make install
After that, I tweaked my /etc/X11/xorg.conf and restarted X. Now I can use tapping and even edge scrolling ! Following is an excerpt from my xorg.conf FYI.
Thank you again, Yoichi.
