Have you tried not specifying any modelines in your xorg.conf at all?
The Geode driver has built in timings for most of the standard VESA
modes that are correctly matched to the PLL.  Just comment
out all of the modelines in your xorg.conf file, make sure
that the vsync and hsync ranges are correct for your monitor, and specify
the resolutions as normal.

If that doesn't get any better, then please send a X log file, and we can
see what modes the driver thinks it is using.
