I have experience testing higher refresh rates, and I plan to test higher refresh rates when I get mine, so I'll be able to verify if it works.
I also made a utility that allows AMD/ATI users to create custom resolutions: http://www.toastyx.net/cru-preview.zip
It's still a work in progress, but it's mostly functional. It works by creating EDID overrides directly in the registry without having to deal with creating .inf files. (Windows XP does not support EDID overrides, so Vista or later is required.) This program will also work for NVIDIA users, but NVIDIA's driver will sometimes ignore a resolution for no obvious reason.
I'll let you know what settings work on my ATI 5670 when I get the monitor.
I'll just copy the release notes that I posted here: http://hardforum.com/showpost.php?p=1038342324&postcount=6
It's a portable program. No installation required. When starting the program, a UAC prompt will appear because it needs permission to write to the registry.
The first active display is loaded when the program starts. If other monitors are present in the registry, the drop-down list can be used to select another monitor. Note that there may be inactive or outdated monitors in the list. You can use the Delete button to mark them for removal. Monitors marked with an asterisk (*) have changes saved.
The first detailed resolution is considered the native or preferred resolution. If you want to play around with higher refresh rates, add a detailed resolution. Note that the pixel clock must stay under 165 MHz for the resolution to work with single-link DVI.
Lower resolutions can usually be defined as standard resolutions. Do not define the native resolution as a standard resolution. You can safely remove any resolutions that you don't need.
The extension block often contains other information like HDTV resolutions and audio capabilities. Do not enable this option if it was not originally enabled. This program doesn't provide a way to edit the extension block since the data is not stored in the registry.
After clicking OK, Windows must be restarted for the changes to take effect. To remove the changes, use the Delete button next to the monitor drop-down list to mark the monitor for removal, then click OK and reboot.
* The monitor name will be lost after changes take effect (but will be restored if the changes are removed)
* The Import/Export buttons are not implemented yet
* The timing drop-down list in the Detailed dialog is not implemented yet
* The interlaced checkbox sets the interlaced bit but does not adjust the values

It's actually the opposite. Several NVIDIA users had trouble with the driver ignoring the resolution for no obvious reason. The only reason ATI users had trouble is because there was no utility to add custom resolutions other than PowerStrip, which isn't free.
