Warren, I need those who has synaptics i2c touchpad device to test the kernel.
We want to make sure the new kernel doesn't break anything and enables the touchpad well.
If you are available, please give it a try and report back, thank you.

Title:
  regression: SynPS/2 touchpad detected as DLL060A:00 pointer

Status in Release Notes for Ubuntu:
  Fix Released
Status in “linux” package in Ubuntu:
  Triaged
Status in “linux” source package in Trusty:
  Triaged

Bug description:
  This regression occurs somewhere between 3.11.0-14-generic (latest on
  saucy) and 3.13.0-031300rc6-generic (a test kernel). On the earlier
  kernel, I actually  get settings for setting up my touchpad in the
  unity interface. With the updated kernel, those options disappear. I
  only get one set of options both my mouse and my touchpad instead of
  each one independently. It means that I can't set the pointer speed
  differently or turn on natural scrolling for my touchpad.

  WORKAROUND: Execute at a terminal and then reboot your system:
  echo "blacklist i2c_hid" | sudo tee -a /etc/modprobe.d/blacklist.conf
