ForceWare too new? :) Which one did you try?

Hm... Actually no one ever asked :)
I'll see what I can do.

The easiest way would just be to recalculate them using standard mode formulas like the GTF, CVT, etc. You may also find an interactive modeline calculator handy, though most are geared toward creating modelines that are "optimal" for PC monitors and will give poor or useless results in this situation. Either of these methods will generally result in a mode that has a higher visible line count since there's a relationship between number of lines and horizontal scanrate at a given vertical refresh rate. For example, you'll probably end up with something like 640x525@50Hz rather than 640x480.
If you want to keep all the sizes the same but reduce the refresh to 50Hz, what you'll do is lower the dot clock (first number) then increase the number of blank lines (easiest way to do that is probably to increase the last three numbers equally). Basically, what you're doing is telling the computer that, while the extra lines exist, you don't want to use them and they should be blank. You'll probably have to do this by hand, though a modeline calculator application may help you verify your results.

Oh, ForceWare can be too new? I have latest installed. Which is a good / ideal version?

hi
Ive done a bit of reading and couldnt find the answer.. but would a geforce 6220 (nvidia) pcie be compatible with soft 15khz?

Yes. Mind the Nvidia 32-resolution limit.
