What Modeline in /etc/XF86Config is currently associated with the
1024x768 mode that you are using? If you can find that modeline and
post it to the list, I should be able to make a working modeline for
800x600 from it that will be compatible with your monitor.

What is your monitors horizontal & vertical scan bandwidth?

The info I am looking for looks something like this (and is in
/etc/XF86Config)

(yes, a plain S3V card and a Princeton monitor sold as a 1200x1024 max
can do a reasonable 1600x1200! 55Hz is a little on the blinky side
though.)
