Thank you. That was really helpful. I'm wondering why there is no good
documentation at x.org.

With the new configuration, xrandr does not show 1280x1024 anymore:

root at stargazer:~# xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
   1024x768       60.0*
   800x600        60.3
   640x480        59.9
DVI-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)

I've put then to try HorzisSync and VertRefresh lines to my xorg.conf:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync    31.5 - 92.0
        VertRefresh  50.0 - 100.0
EndSection

Finally, xrandr was showing more options:

root at stargazer:~# xrandr
Screen 0: minimum 320 x 200, current 1152 x 768, maximum 1280 x 1024
VGA-0 connected 1152x768+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
   1280x1024      85.0     75.0     60.0
   1280x960       85.0     60.0
   1152x864       75.0
   1152x768       54.8*
   1024x768       85.0     75.0     70.1     60.0
   832x624        74.6
   800x600        85.1     72.2     75.0     60.3     56.2
   640x480        85.0     72.8     75.0
   720x400        85.0
   640x400        85.1
   640x350        85.1
DVI-0 disconnected (normal left inverted right x axis y axis)
S-video disconnected (normal left inverted right x axis y axis)

With the HorizSync and the the VerRefresh options in the xorg.conf, I
was able to change to 1280x1024 with xrandr. I've added then the Virtual
option to the Screen section:

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Virtual   1280 1024
        EndSubSection
EndSection

Unfortunately, that doesn't work. If that would work, I would be totally
happy.

I haven't done that, because I thought the new config file should be fine.
