Maybe it was trying to use another depth (like 16), and because it
wasn't present in a "Display" subsection it used all the available
modes by default.

You can only use the modes that are listed in "Modes", that's why you
can't switch to 1280x1024. You have to add "1280x1024" to the "Modes"
line (when not using DefaultDepth 24 it seems all modes are listed
there).
Then X will start in the higher resolution it can find in "Modes", to
solve this you can put in .xinitrc the following command (which will
change the resolution after X starts):
xrandr -s 1024x768
You can also see the list of available resolutions with that command
(without parameters).
If you have something like "exec /usr/X11R6/bin/xfce" in .xinitrc be
sure to put the "xrandr -s 1024x768" command before it (the "exec"
replaces the shell by xfce, so everything after the exec will never
be executed).
For example (xorg.conf section with 1280x1024 added to Modes):
Section "Screen"
Identifier "Screen0"
DefaultDepth 24
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768"
EndSubSection
EndSection
