Knowing how difficult it is to set up modelines in XFree86 (the HOWTO even uses the term "black magic"), I thought I'd post some modelines that I've successfully tweaked my VL700 with. These may or may not work for you; I make NO guarantees of any kind; in fact, if you have a cheaper multisync monitor, improper modelines can PERMANENTLY DAMAGE your monitor. You have been warned.
Here's an entry for XFree86 4.0. I have not tested this with any modes above 1152x864:
Section "Monitor" HorizSync 30-70 VertRefresh 40-170 EndSection
NEW! If you want even higher refresh rates, then try this. But be prepared to adjust your geometry settings. Alternatively, just run xvidtune and make the image wider and taller.
Section "Modes" Identifier "Modes[0]" # 1024x768 @ 88.95 Modeline "1024x768" 94.50 1024 1072 1168 1328 768 769 772 800 # 1152x864 @ 79.7 Modeline "1152x864" 108.00 1152 1216 1344 1504 864 865 868 896 EndSection
And here's the old entry for XFree86 3.x:
