Jikes! That summons my touchpad back to life. Thanks, that's great!
How could one automate that workaround?
And what would be the right place/moment to do it?
I saw the following appear in dmesg before and upto suspend:
Code:
[ 7661.764038] PM: Entering mem sleep
...
[ 7662.344543] PM: late suspend of devices complete after 16.662 msecs

[ 7662.346879] PM: Saving platform NVS memory

I saw the following appear in dmesg after the resume:
Code:
[ 7662.346884] ACPI: Low-level resume complete
[ 7662.346884] PM: Restoring platform NVS memory
[ 7662.346884] Force enabled HPET at resume

I saw this happen when I did the modprobe that fixes the touchpad:
Code:

[ 7805.599690] psmouse serio4: elantech: touchpad refuses to switch to absolute mode.
[ 7805.599703] psmouse serio4: elantech: failed to initialise registers.
[ 7805.599713] psmouse serio4: elantech: failed to put touchpad into absolute mode.
[ 7806.090532] input: ImPS/2 Elantech Touchpad as /devices/platform/i8042/serio4/input/input8
Any idea what went wrong?
