The VESA 2.0 video card standard only supports resolutions at a 60Hz refresh rate. Vesa 2.0 compatible programs like xvesa cannot tell the video card to use a different refresh rate.
However, many modern video cards (say 1999 and newer) support the Vesa BIOS exension 3.0 and you can set your own refresh rate with these extensions.
Unfortunately, the xvesa server does not currently support the VBE 3.0 refresh setting commands.
So the only way to get a refresh rate higher than 60Hz is:
(1) Install the full-blown XFree86 windows server instead of the xvesa KDrive server.
(2) If you are a programmer, hack up the xvesa source code and create a version of the program that works with VBE 3.0 refresh rate commands.
(3) Use the frame buffer server (xfbdev) for XWindows, but you need to somehow start up a frame buffer than is running at a higher refresh rate on bootup so that xfbdev will also run at the higher rate.
Good Luck
