Xorg is not accepting a good display mode.

I am using a wide-screen monitor but Xorg is claiming that the 1366x768 display mode is invalid but when I use the xvidtune program to set the display to the same settings I have in the xorg.conf file, it works just fine.
Here is the relevant excerpt from the xorg.0.log:
(**) SIS(0): Option "NoDDC" (==) SIS(0): Min pixel clock is 5 MHz (--) SIS(0): Max pixel clock is 168 MHz (II) SIS(0): Monitor0: Using hsync range of 31.50-50.00 kHz (II) SIS(0): Monitor0: Using vrefresh range of 25.00-65.00 Hz (II) SIS(0): Clock range: 5.00 to 168.00 MHz (II) SIS(0): Not using mode "1366x768" (illegal horizontal timings)
I am using FC11 but when I was using FC8 (I just upgraded) it accepted the wider video mode just fine. Since the hardware configuration did not change between the two versions, there must be a bug with the newer software.
