Aiptek Slim Tablet 600U

I just got me a new Aiptek Slim Tablet 600U, and would like to configure this on opensuse, but it is not working as expected. I would very much like the tablet set to “absolute”.

I found this forum thread for Ubuntu, but this it not working in openSUSE.

anybody?
when I try to modify my xorg.conf, and then try to restart x, it won’t work.
