Is it so that there are no software solutions to set DOS refresh rates for Radeon 9000 cards?
UniRefresh supports only VESA 3.0 so ATI cards vith 2.0 are no go.
I have found some discussion on this board about BIOS modding refresh rates in order to mate DVI output with modern LCD displays.
My interest however would be getting 640x480; 800x600 and 1024x768 working at 75Hz or better on CRT monitor.
Any good resources/links I could read up about tools and techniques about that? I have cheap 9600 card for experiments...

Last time I stumbled over that topic, I heard mentions that BIOS editing is the way to go. The Tool "RadEdit" had the option to change those, haven't tested it personally though. Perhaps worth a look.

For whenever you play around with the VBIOS, have a PCI card ready so you can flash it even if you screwed something up.
