Disable screen/power save on QSB

We've got an LTIB image up and working on the QSB.  We're running Gstreamer commanded through the serial terminal and displaying video on the VGA port (Video16).  However, the screen goes blank after a few minutes.

Where is or what can I change to prevent the video from going to power saving mode?  I need the display to stay on permanently.

Thanks!

In vt.c under ltib/rpm/BUILD/linux/drivers/char disable line 2399 : ' do_blank_screen(0); ' 

try it, it can be.

We're looking under /sys/devices/platform and trying to find the right device to reconfigure power management.  Any suggestions?
