i2c-i801 is loaded.
touchpad is detected as s3203_ver5.
Could you try this kernel with i2c_i801 unblacklisted?

I added bionic-proposed to a broken machine and verified the installed
version is 24-1ubuntu3.2 and that the blacklist.conf file had the proper
blacklist entry. However I noticed that apt did not run update-
initramfs.
After a reboot the touchpad was still not working. After manually
running
Opened "linux" task for investigating the real root cause of this
regression.
