This isn't a driver issue.  That command forces the displays on.  If you run
'xset dpms force off'  your monitors be forced off.  If you run 'xset dpms
force on' your monitors will be forced on.  forcing an output on or off may
include some flicker depending on what programming sequence is required to do
it.  What xine is doing is abusing that command to prevent the screen saver
from kicking in by repeatedly executing it.
