Actually, I want to do this because in a couple months I'm going to do stereo 
graphics with X. So in order to get 60Hz per eye, I'll have to get 120Hz 
overall.

I looked at the programs, and I was wondering if anyone had any experience 
with any of them? I'd rather not screw up my monitor because I used bad 
software. Is there a reliable way to extrapolate other mode lines from known 
mode lines, or is it more complex than that?

Thanks,
Tom
