My monitor doesn't draw the top few lines of the screen when I've set the 
vertical retrace interval too short (not a Thinkpad or LCD).  Maybe that's 
related?

Mode "my_1024x768"
        Dotclock 60
        Htimings 1024 1080 1176 1232
        Vtimings 768 773 776 795
EndMode #        aaa bbb bbb aaa     The difference between aaa:s is
        #        the vertical retrace interval (in units of lines);
        #        the difference between bbb:s is the pulse width
