Here is my xorg.conf file. I use a SB100 with a Sun 19" LCD. Get the Horizantla and vertical refresh rates for your display and all should work. make sure to round up for the lower limit and round down for the upper limits. mine were
31.5 kHz to 81.1 kHz Horizantal
56.0 Hz to 76.0 Hz Vertical
and I set them for HorizSync 32-81 VertRefresh 56-76
