I've NEVER EVER needed to put any modeline in any distro's xorg.conf, and I
do a LOT of testing with different distro versions, Xorg versions, CRT and
LCD displays, gfxchips and video drivers. Xorg calculates the modelines it
needs if it has any valid data about the hardware. Usually EDID is
sufficient. When not (e.g. invalid EDID), all it needs is the display's
HorizSync and VertRefresh ranges, and the desired resolution.

IOW, don't waste your time on modelines unless you like wasting more time on
an already tedious task, or you've tried absolutely everything else, without
success.
