Actually I ended up installing the kvideogen rpm from the 2nd Mandrake 7.2 CD as opposed to firing up a previous version of X. This is a neat-o program that creates a text file with Modelines with the best refresh rates your monitor can handle. I did have some trouble when I tried inserting the Modelines into XF86Config (per the directions), but eventually i figured out the X version thing and stuck them in XF86Config-4. Now I'm humming along at 107.1Hz! Thanks, Phil R Lawrence
