Comment 90 for bug 1861610

@Ferenc: I have similar results as Filip.
Followed the fix (#66), used the correct sed command (with backslash #86) and updated grub... still no touchpad, even though output of 'lsmod | grep i2c' is:
i2c_algo_bit 16384 1 i915
elan_i2c 40960 0
i2c_i801 32768

And output of 'll /sys/bus/i2c/drivers/elan_i2c/' is:
total 0
drwxr-xr-x 2 root root 0 avg 10 20:26 ./
drwxr-xr-x 40 root root 0 avg 10 20:26 ../
--w------- 1 root root 4096 avg 10 20:44 bind
lrwxrwxrwx 1 root root 0 avg 10 20:44 module -> ../../../../module/elan_i2c/
--w------- 1 root root 4096 avg 10 20:26 uevent

I have ubuntu 20.04 kernel 5.4.0-42-generic, although my laptop is Thinkpad 14 IIL. Any ideas?
