You'll like this! On one of my machines:

   brian@dektop3:~$ lspci | grep VGA
   01:00.0 VGA compatible controller: NVIDIA Corporation NV34 [GeForce FX 5200] (rev a1)

You can compare mine with yours:

   brian@dektop3:~$ xrandr
   Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
   VGA-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
      1280x1024      63.2*+
      1024x768       60.0  
      800x600        60.3     56.2  
      848x480        60.0  
      640x480        59.9  
   VGA-2 disconnected (normal left inverted right x axis y axis)
   TV-1 disconnected (normal left inverted right x axis y axis)

If I was in your situation and was after 1280x1024 I'd put this in
an /etc/X11/xorg.conf:

   Section "Screen"
       Identifier    "Default Screen"
       DefaultDepth   16
       SubSection "Display"
           Depth      16
           Modes     "1280x1024"
       EndSubSection
   EndSection
