I don't know if this works with all LC-Displays but I've disabled the
automatic mode detection (Option "NoDDC") and use these modelines to
get unscaled and scaled modes:

# 75Hz Modes
  # native resolution, centered
  Modeline      "1440x900"  136.50   1440 1536 1688 1936   900  901  904  940
  Modeline      "1200x900"  136.50   1200 1416 1568 1936   900  901  904  940
  Modeline      "1024x768n" 136.50   1024 1328 1480 1936   768  852  855  940
  Modeline       "800x600n" 136.50    800 1200 1352 1936   600  768  771  940
  Modeline       "640x480n" 136.50    640 1128 1280 1936   480  720  723  940

  # 4:3 scaled to max height, horizontally centered
  Modeline      "1024x768"   99.13   1024 1168 1280 1648   768  771  774  802
  Modeline       "800x600"   59.44    800  920 1024 1264   600  601  604  627
  Modeline       "640x480"   37.35    640  736  816  992   480  481  484  502

  # 16:10 scaled to max height, full width
  Modeline      "1280x768"   99.13   1280 1300 1428 1648   768  771  774  802
  Modeline       "960x600"   59.44    960 1008 1112 1264   600  601  604  627
  Modeline       "768x480"   37.35    768  800  880  992   480  481  484  502

Works very well on a Fujitsu-Siemens Scaleoview W19-1 connected via the
analog VGA plug.

Ciao, ET.


PS: Yes, I know, 1280x768 is not exactly 16:10 ...
