Can someone summarize the current state of this? Is there anything
affected users can do or provide to help fix this issue?

I'm on a Thinkpad X1 Carbon 6th Gen. (20KGS5DU00) with NFC touchpad.
Running Ubuntu 19.04 with 5.0.0-31-generic kernel.

fwupdmgr shows no updates currently:
System Firmware is 0.1.41.
UEFI Device Firmware is 184.65.3590.
UEFI Device Firmware is also 0.1.17.

I use S3 sleep mode and when the laptop wakes up with a non-functioning
touchpad I run the following command (which is mentioned in the entry
post) a few times. If the touchpad doesn't come back to life I suspend
again and repeat the cycle until it works.

echo -n none > /sys/devices/platform/i8042/serio1/drvctl && \
  echo -n reconnect > /sys/devices/platform/i8042/serio1/drvctl \
  rmmod psmouse && \
  modprobe psmouse
