1) You're missing a section like the following for my monitor:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection
2) Your monitor cannot go higher than 1024x768.
If it is case 1) then use /usr/bin/system-config-display and configure
your monitor for 24-bit color.
