Use the 'gtf' program to generate new modelines for your XF86config file.
I think it is in /usr/X11/bin/.
The syntax would be
gtf <horizontal-resolution> <vertical-resolution> <vertical refresh> -x
Make sure that your monitor can handle the new resolution.
If you increase the resolution beyond 1280x1024, you may need to reduce the colors (i.e. use 16 bit instead of 24 bit) so that you don't run of video memory.
Also, use the gtf command on an unloaded machine, for better results. In other words, don't have a lot of programs running.
