Try installing gsynaptics, it doesn't seem to link to the launcher menu but you can run it from command line: #gsynaptics . It's not ideal as as doesn't persist over a reboot but it may help determine whether it's a synaptiks / KDE issue or a kernel/module issue. Can you see anything relevant in lspci / lsmod?
I'll give gsnyaptics a try. Here is what I got when I entered Ispci & Ismod: (not sure what any of it means)
