I had the same problem with my ati card and the binary driver. Adding a
line "VertRefresh 50-60" in the monitor section of xorg.conf helped.

Here is the monitor section of my xorg.conf:
Section "Monitor"
Option "CalcAlgorithm" "XServerPool"
DisplaySize 376 301
HorizSync 30-83
Identifier "Monitor[0]"
ModelName "CM2019"
Option "DPMS"
VendorName "ICP"
VertRefresh 50-60
UseModes "Modes[0]"
EndSection
