I pulled today's commits from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git which build as kernel 3.18.0 showing still the same issue.

Additionaly I took the opportunity to upgrade my ACER B115's BIOS from V1.22 to V1.26. Luckily I had to reset my personal settings back and with this I also took a deeper look into the BIOS settings. There I discovered a setting under MAIN->TOUCHPAD=ADVANCED. This seems to be the "default" with an additional note like: ...take care the I2C driver is loaded first if using advanced setting...
I decided to set this to BASIC instead and since then the Synaptic touchpad is recognised UNDER 14.10 as with previous Ubuntu 14.04.

I assume the I2C_HID recognition does not yet work as supposed to since the dmesg with TOUCHPAD=ADVANCE under 3.16 showed

i2c_hid i2c-SYN1B7D:01: failed to retrieve report from device.

which it does not under the BIOS setting MAIN->TOUCHPAD=BASIC <strange>.
