Ok, so I'm now using 4.9.0-040900rc1-generic kernel. For a hour or so I
thought that everything is good but then touchpad stopped working for a

xinput.
I added a kernel-bug-exists-upstream tag.

As you can see from the logs above I've just booted on mainline kernel
and the issue is still there. Now It's actually what it was a while ago:
Elantech touchpad detects as Logitech PS/2 Mouse.
Hope that helps you.

Here is what I was able to collect running Ubuntu from external USB HDD.
The touchpad is currently working but it's a rather random issue that
can appear after reboot or waking from sleep.
If you need more info please do not hesitate to request it.
