Did some more digging.

- Kernel 4.10-rc1 - the same
- /dev/input/eventX - does not even fire multitouch events, so no luck here
- Tried sniffing bluetooth data with hcidump - and, oddly, this does not fire multitouch events also!

So probably, the driver has to request multitouch support from the device explicitly, which does not happen, Can't find any technical documentation for the touchpad microcontroller so I think we are out of luck
