The one posted to the XFree86 list uses the Vesa GTF standard so it's essentially the vesa-recommended way of doing it. Eric Raymond wrote a large amount about modeline specifics at http://www.ibiblio.org/mdw/HOWTO/XFree86-Video-Timings-HOWTO/ with formulas and such in case you want to know the particulars of what the timing parameters mean.
