Hi! Managed to reproduce the steps described in #211 (using the updated
archive provided in #217) and #212. The touchpad seems to be working
after running

$ sudo rmmod i2c-hid
$ sudo insmod full-path/i2c-hid.ko polling_mode=1

I need to provide the full path to the i2c-hid.ko module, otherwise the system 
returns "could not load module "i2c-hid.ko: No such file or directory"; not 
sure if this is already an issue.
However, I am not sure how to add the boot parameter to GRUB. I followed this 
(https://wiki.ubuntu.com/Kernel/KernelBootParameters) and tried adding either 
one of these three options:

i2c-hid.polling_mode=1
full-path/i2c-hid.polling_mode=1
full-path/i2c-hid.ko.polling_mode=1

but neither seems to be working. Am i doing something wrong? Using
Ubuntu 20.04.1 with kernel 5.8.16. Also, total noob and first time
writing here, so hopefully not causing issues.
