There are a couple of items that could cause this:

1) the nvidia driver has dropped support for the video card you have.
however the xvesa card should work at 1024x768
2) more likely the monitor does not have a DMI probing and so the
video driver goes into safe mode of 800x600.

There are a couple of ways to try and fix this.
1) Make a custom xorg.conf file with the display set up for it.
2) Use xrandr to do it on the fly

xrandr --newmode "1024x768" .... fill in data for your monitor here
.... +hsync +vsync
xrandr --addmode VGA1 "1024x768"
xrandr --output VGA1 --mode "1024x768"x0.0

or something like that.

Ah, but a man's reach should exceed his grasp. Or what's a heaven for?
