It's a little hard to know, because there are no timestamps in the
pm-powersave.log file, it just gradually grew without me noticing until
it was multiple gigabytes... so I have no real idea how long it's been
an issue.

Correct.

Will give some systematic downgrading a try...

Ah, that would explain things a bit if two things are fighting over
resume events somehow...

Understood; will try to find out more...
