Touchpad not found / working

Hello

I installed OpenSUSE 12.3 x64 with KDE on my Medion akoya E5218. Everything is fine with the drivers, except the touchpad. Its dead, also at the loginscreen, and when I open the config menu, it just says: no touchpad found. I googled a lot and tried to reinstall the synaptiks pack, now xf86-input-synaptics 1.6.3-1.1.1 (1.7.1-1.2) is installed. I have no idea what else i could try. Any suggestions?

Thanks.
