Had the same problem with my L3H series (sis650). The following solved the problem for me:
Section "Monitor"
HorizSync 15-61
Identifier "Monitor[0]"
ModelName "Unknown"
Option "DPMS"
VendorName "Unknown"
VertRefresh 30-90
UseModes "Modes[0]"
EndSection
Section "Modes"
Identifier "Modes[0]"
Modeline "1024x768" 71.39 1024 1040 1216 1400 768 768 777 802
Modeline "1024x768" 81.01 1024 1040 1216 1400 768 768 777 802
EndSection
Section "Device"
BoardName "SiS650"
BusID "1:0:0"
Driver "sis"
Identifier "Device[0]"
VendorName "SiS"
EndSection
Let's hope this (or slightly edited) works for you too.
Also the version of XFree is important. You need 4.3.x, not 4.2.x.
