(Posted for the record, not intended to be read.)
Here is a list of users' reports about PS/2 -> smbus migration of synaptics. I will (probably) send a patch, which has to be tested by users. (Thus it will be a "v0" one. Still a long way to go. :p)
I group the reports (roughly) into 3: devices that can use smbus without troubles, devices with some failure, and Lenovo Carbon X1 Generations 5 and 6.
In the following, users' posts to linux-input@xxxxxxxxxxxxxxx from Jun 2017 to May 2018 are collected. The list is almost exhaustive, if not complete, I believe.

* Failure reports
Major failures are : (a) resume/suspend (b) Kernel stack traces - seemingly unrelated modules of drm or videodev. One is about irq.

* X1 Carbon 5th/6th gen
The story is complicated with Gen 5. Probably 6th gen is ok.
Anyway, these were included in Linux-4.17:
LEN0092, LEN0096, LEN0097 (6th Gen and others)
LEN0071, LEN0072, LEN0073 (5th)
See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/input/mouse/synaptics.c?h=v4.17
LEN0091 was not included there.
