Indeed, it doesn't work.

I tried to rmmod i2c_designware_platform on my installed system, the
mouse stopped working, so it seems to be required, at the very least.
I tried to add i2c-modules to a g-i image, i2c_designware_platform
didn't get loaded automatically, and even loading it manually didn't
make the mouse detected.
