OK. So I tried this:
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 30-95
VertRefresh 50-160
Modeline "1400x1050" 184.00 1400 1464 1656 1960 1050
1051 1054 1100 +hsync +vsync
# 1400x1050 84.96 Hz (CVT 1.47M3) hsync: 93.88 kHz; pclk: 179.50 MHz
Modeline "1400x1050_85.00" 179.50 1400 1512 1656 1912 1050 1053 1057
1105 -hsync +vsync
# 1400x1050 74.87 Hz (CVT 1.47M3) hsync: 82.28 kHz; pclk: 156.00 MHz
Modeline "1400x1050_75.00" 156.00 1400 1504 1648 1896 1050 1053 1057
1099 -hsync +vsync
# 1400x1050 59.98 Hz (CVT 1.47M3) hsync: 65.32 kHz; pclk: 121.75 MHz
Modeline "1400x1050_60.00" 121.75 1400 1488 1632 1864 1050 1053 1057
1089 -hsync +vsync
Option "PreferredMode" "1400x1050"
EndSection
The 60 an 75 Hz variants work under 6.8.0, the 85 Hz doesn't.
Strange. you might try tweaking it slightly, maybe 87 Hz, etc.
