This problem persists with Ubuntu 20.10 released today.

FWIW, I do this dance after boot and the touchpad works...
➜ ~ sudo modprobe psmouse

The problem persists on 5.4.0-48 sadly, I still need to select advanced in
grub, selecting 5.4.0-42 for the touchpad to work.
*➜ ~ xinput --list*
*5.4.0-42*
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer
Kernel 5.4.0-48 fixes the problem. The TouchPad is recognized correctly
and touch pad, buttons, and track point work. Thank you.

Same issue. Lenovo Thinkpad X1. Looks like it started with kernel version
5.4.0-45 and remains in 5.4.0-47. With 5.4.0-42 trackpad is listed as
↳ SynPS/2 Synaptics TouchPad
in xinput, with 5.4.0-45 and 5.4.0-47 it shows as
↳ Synaptics TM3418-002
according to Xorg.0.log same driver is loaded
