I have a very similar laptop (Fujitsu-Siemens Amilo M1439G) - same problems including non detection exactly as FriedChicken described it and the nvidia driver incompatibility. Thanks to Zeppe, who put me on the right track, I have gotten the trackpad working. Essentially after using his InputDevice section, Xorg detected the pad but then wouldn't react to my finger.
I then removed (almost) all his options, installed gsynaptics (it wouldn't start before but now works....), and was able in increase the sensitivity until my finger was detected. It is working well now. My device section from xorg is very trimmed:

Section "InputDevice"
       Identifier "Synaptics Touchpad"
       Driver "synaptics"
       Option "SHMConfig" "true"
       Option "Emulate3Buttons" "on"
EndSection

note: in the ServerLayout Section I added the line:
    InputDevice "Synaptics Touchpad" "SendCoreEvents"

Hope that solves it for you too friedchicken,
