I don't know if there is an easier way, but I just copy the modelines
I like from the log and paste them in the xorg.conf file. Put them in
the "Monitor" section.
E.g.:

ModeLine "1600x1200"  162.00  1600 1664 1856 2160  1200 1201 1204 1250
+hsync +vsync

I use modelines that give 60Hz vertical sync because there is a
transformer sitting next to my monitor, and at 70Hz sync rate the
display wiggles at 10 Hz.
