Not sure if 'me too' reports are welcome, but... I too am hit by this problem, on different touchpad hardware. Downgrading the xserver packages back to the previous versions in Jessie (1.15.99 --> 1.15.1) restored touchpad functionality. That process downgraded all xserver packages, including xserver-xorg-input-synaptics from 1.8.0 --> 1.7.3.
The only differences apparent in Xorg.0.log between working and non-working appear to be various version numbers, and event numbers in /sys/devices paths...
