[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?
