None of my machines have an xorg.conf with a sample modeline for that.

Could someone post an example I could try please?

Or even better, are there docs someplace that would describe how to do 
that?  I just looked at the modeline description in a man xorg.conf, and 
that lacks the specifics I'd need to make a quasi-intelligent first guess.

Thanks all.
