I managed to have my touchpad working now. I had the following xorg.conf section:

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "AlwaysCore"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/input/event4"
 Option "Protocol" "event"
 Option "SHMConfig" "true"
 Option "LeftEdge" "130"
 Option "RightEdge" "840"
 Option "TopEdge" "130"
 Option "BottomEdge" "640"
 Option "FingerLow" "7"
 Option "FingerHigh" "8"
 Option "MaxTapTime" "180"
 Option "MaxTapMove" "110"
 Option "ClickTime" "0"
 Option "EmulateMidButtonTime" "75"
 Option "VertScrollDelta" "20"
 Option "HorizScrollDelta" "20"
 Option "MinSpeed" "0.90"
 Option "MaxSpeed" "2.50"
 Option "AccelFactor" "0.30"
 Option "EdgeMotionMinSpeed" "200"
 Option "EdgeMotionMaxSpeed" "200"
 Option "UpDownScrolling" "1"
 Option "CircularScrolling" "1"
 Option "CircScrollDelta" "0.1"
 Option "CircScrollTrigger" "2"
 Option "Emulate3Buttons" "on"
EndSection

I changed the Device to /dev/psaux, the protocol to auto-dev, and I removed the line AlwaysCore, i.e.:

Section "InputDevice"
       Identifier "Synaptics Touchpad"
       Driver "synaptics"
       Option "SendCoreEvents" "true"
       Option "Device" "/dev/psaux"
       Option "Protocol" "auto-dev"
       Option "SHMConfig" "true"
       Option "LeftEdge" "130"
       Option "RightEdge" "840"
       Option "TopEdge" "130"
       Option "BottomEdge" "640"
       Option "FingerLow" "7"
       Option "FingerHigh" "8"
       Option "MaxTapTime" "180"
       Option "MaxTapMove" "110"
       Option "ClickTime" "0"
       Option "EmulateMidButtonTime" "75"
       Option "VertScrollDelta" "20"
       Option "HorizScrollDelta" "20"
       Option "MinSpeed" "0.90"
       Option "MaxSpeed" "2.50"
       Option "AccelFactor" "0.30"
       Option "EdgeMotionMinSpeed" "200"
       Option "EdgeMotionMaxSpeed" "200"
       Option "UpDownScrolling" "1"
       Option "CircularScrolling" "1"
       Option "CircScrollDelta" "0.1"
       Option "CircScrollTrigger" "2"
       Option "Emulate3Buttons" "on"
EndSection

and now it just works.

Hopefully this will solve other people's problem.
