I had the same problem with a ThinkPad T440s on Ubuntu 19.10 beta. (Just that there was no blacklist entry in /etc/modprobe.d/blacklist.conf so I used "modprobe i2c_i801" instead.)

However, when I instead use the module name with a "-" instead of "_":

    modprobe i2c-i801

then it works immediately to restore two-finger scrolling, and two-finger scrolling keeps working after a suspend-and-resume cycle.

In other news, this bug is still present in Ubuntu 19.10.
