When I was playing around with modelines (using 480p, through a
VGA->Component converter), I accidentally got my Sony CRT HDTV to  
switch to widescreen mode.  I was using xvidtune at the time.  Try  
playing around with the front and/or back porch settings; also try  
playing around with the +/- horiz/vert sync settings.  This experiment  
might be easier in PowerStrip (Windows) since IIRC it allows you to  
lock the H and V frequencies.

You might also try asking in the HTPC forum over at avsforum.com
