The reason your monitor is going blank is because it can't use the frequencies 
that the video card is putting out. To protect itself it turns off.

If you know the sweep frequencies of the monitor and the resolution you will 
be using, edit these sections of /etc/X11/xorg.conf (these are mine for a 
sample) and enter the numbers into your file;
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Digital Electronics"
        ModelName    "Digital 21 in. Color (FR-PCXAV-WZ)"
        HorizSync    30.0 - 85.0
        VertRefresh  50.0 - 120.0
        Option      "dpms"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     16
                Modes    "800x600" "640x480"
        EndSubSection
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x1024" "1280x960" "1152x864" "1024x768" 
"800x600" "640x480"
        EndSubSection
EndSection
