So, with my usual kernel version, 5.4.0.40-generic, adding that line (exactly as it was written, including spaces, " and ' ) during boot ('e' -editing the grub), the touchpad works, but after the laptop goes idle or the screen is locked, it goes back as a generic mouse.
The trick of disconnecting and connecting it back with ```modprobe psmouse``` keeps working though... I am trying it now with the latest version of the kernel 5.8.0-050800-generic. The touchpad works from start. I have locked the screen and it keeps working after logging in. Even better, all the multi-finger movements work as well ( I had fusuma, but 4 finger vertical swipe never worked; now, it is working). I can't say yet that it has been fixed, but definitely we're on the right track! Please let me know if I can do anything else to help you debug this thing.
