[PLUG] Setting the Refresh rate for FC5???

I am using FC5 with a Dell E173FP flat screen.
The monitor claims that 1280 X 1024 @60Hz is the "optimal" setting.
The only refresh rate that is selectable is 75Hz.
XP has no problem offering a 60Hz refresh.
At 1280 X 1024 @75Hz resolution some of the smaller text flickers.
I am unable to set the refresh rate to 60 Hz
I have poked at xorg.conf.  
There does not seem to be a setting in there for refresh rate.
Below is the EDID data pulled from the display.
