If that stops the lockups, then you could try setting each in turn to

one being tested. But these also seem unlikely, as it's a hardware
signal from the video board to the monitor. The suggestion of an X
screensaver causing the lockup was excellent. Even if you have no
screensavers, there are other things that could be triggered, like
xlock.
Not sure I understand what you're getting at. By "other things that
could be triggered" what do you mean? e.g. xclock obviously gets
"triggered" at least once per minute; you're suggesting that event
could be causinging an update request while blanked out that is
causing trouble?
Other long-term events that happen might be to blame, not related to
screen blanking at all. For example, a cron job.
