Every day the last few days at precisely 17:00, my openSUSE-13.1 system
begins thrashing furiously and becomes unusable for 1-2 hours or so.
I've been trying to figure out what runs at that time, but the system
has again become too unresponsive for me to find out. Also, since it
appears to be I/O bound, it doesn't show up in the "top" display.

sounds like you have a job scheduled to run at "17:00", perhaps cron or a
database update or ....

Or log rotation?

Yes, the system is using quite a bit of swap space presently, and I am
not yet able to kill off any more processes to free up VM space (which I
hope to do as soon as I have some spare cycles to take the time to do
it). Yes, I'd very much like to have a system with more RAM, etc., but
I do not have that now.

And that sounds like you may have a file system full or nearly so.

One of the lists I read had a thread lately (but I remember not where) about
a runaway system logger rapidly running / out of space. Maybe rotation there
is scheduled for 17:00 by fallback default if rotation based on file size
isn't suited to the installation?

Hmmmmm, didn't think of log rotation. Another thing to check.
