Further investigation reveals that this only occurs when S3 suspend is enabled in BiOS. The default that is shipped is identified as s2idle in systemd (just called "Windows 10 and Linux" in BiOS[1]) and is a sort of software suspend that does not preserve much battery time (which is also why I switched to S3). S3 is suspend to RAM I think.
I have upgraded to a new BiOS release that was made available today (N32ET68W 1.44), and an update to the Embed Controller. This did not help with the issue unfortunately. Seeing as the touchpad works fine with the software suspend, but not the S3 RAM suspend, is there perhaps some module that is not handled correctly when waking up from a more thorough suspend?
