This HOWTO is effectively obsolete. Current (4.0.1 and up) versions of XFree86 compute optimal modelines from the resolution you specify in the Modes section of your X configuration file.
How to compose a mode line for your card/monitor combination under XFree86. The XFree86 distribution now includes good facilities for configuring most standard combinations; this document is mainly useful if you are tuning a custom mode line for an ultra-high-performance monitor or very unusual hardware. It may also help you in using kvideogen to generate mode lines, or xvidtune to tweak a standard mode that is not quite right for your monitor.
