In the end, I did it that way. Using psmouse.proto=imps also means I
lose the speed/sensitivity settings on the TrackPoint, and the new
defaults are not really usable for me (following the advice in that
thread, I've set them to 105 and 160, now I need to cook an udev rule or
something to set them at boot).

I tried to generate i8042.debug logs for:

- BIOS touchpad disable / psmouse.proto=imps
- BIOS touchpad enable  / psmouse.proto=imps
- BIOS touchpad disable
- BIOS touchpad enable

but the logs for the two last ones are imcomplete, I get:

Mar 20 12:53:21 balvenie systemd-journal[368]: Missed 2672 kernel
messages

so I miss the initialization which I guess is the most useful part.
