I have mailed earlier to this list what causes this problem and I
believe someone filed it as a bug to the package maintainer. The video
modes that XF86Setup generates are only the optimal ones for 8 bpp.
This means that it is possible that your video card cannot provide
these optimal frequencies at larger color depth. A workaround can be
to run XF86Setup again and pretend that your monitor has a lower
maximum vertical refresh rate. You'll have to experiment a little to
find out how low the frequency should be to get your desired resolution
