I just tried loading the modules manually, and it didn't help:

Specifically I used modprobe to make sure hid_multitouch intel_lpss_pci
and i2c_hid_acpi were loaded, and this didn't help.

I also tried loading i2c_designware but there was no such module. This
would explain why :-D

I could also try creating a diff between modules loaded in the installer
and on the installed system and load them one by one (if available) looking
if this helps.
