Try adding something like this to your XF86Config:

Section "Monitor"
  Identifier	"Gateway CM751"
  VendorName	"Gateway"
  ModelName  	"CM751"
  HorizSync  	30-95
  VertRefresh  	50-160
  DisplaySize 	360 270

XFree tends to use the maximum values given. With analog
monitors quality of what is displayed tends to be reduced
when you get close to the hardware limits.
So i would be a little conservative on the maximum numbers,
maybe start out with "HorizSync 30-85". That should give
you about 88Hz when running at 1280x960.
