Re: 8178 doesn't obey xorg.conf refresh settings
The fact that your Xorg.conf is ignored could be related to the Xserver reading the vrefresh frequency from your monitor's EDIDs ones. Try adding the line:
Option "UseEdidFreqs" "false"
in your device section in Xorg.conf. This could help, and would be a solution, rather than a workaround.

Any sufficiently advanced bug is indistinguishable from a feature.
