[conspire] X Display blanks out after 7 minutes

Happy Thanksgiving folks!
I've solved a number of problems with the new OpenSuSE 10.3,
but this one has me stumped. Exactly 7 minutes -- 420 sec. --
after the last keystroke or mouse movement or click, my display
blanks out. I would like to prevent this, because the display
has a long-standing hardware problem -- every time it powers up
it gets jittery for a while, and I'm afraid that could become
permanent, so I don't want to stress it.
I'm running OpenSuSE 10.3 with KDE 3.5 on an ASUS A7N8X Deluxe
motherboard, I boot with the options acpi=off and apm=off.
The KDE kpowersave demon is not running, but when it was running
I set all four schemes to leave the display alone. The BIOS
doesn't permit turning off its power management completely,
but I set it to do screen blanking instead of DPMS (turning off
the sync pulses to cause the CRT to power down) but the CRT does
power down (sometime after 7 minutes). Nothing is printed in
/var/log/messages or dmesg when the display blanks. I've looked
in /proc and can't find anything that seems relevant.
In single-user mode (boot option "single"), the display blanks
after exactly 10 minutes. So I figure it must be X doing this,
but I've searched through /etc/X11 and can't find anything
relevant. xorg.conf had an Option of DPMS for the monitor,
which I removed, but the display still gets powered down.
I've appended a ps listing of non-personal processes. Can anyone
tell me what this one is: "-:0" (PID 2092)? Or what it means when
the program name is in [brackets] and occupies no memory?
