After a little experimentation, this behavior correlates perfectly with
a running ksysguardd.  When the ksysguard applet is present, ksysguardd
has /proc/acpi/{battery,fan,thermal_zone} open.  I suspect that this
causes problems to the battery module [un]loading through the
suspend/resume scripts, as suggested by some of the log messages (see my
original message in this thread).

Stopping ksysguardd by removing the applet makes this problem go away.
I'll keep looking for workarounds.
