 I don't use xorg.conf in my notebook Lenovo T61, Intel 965GSM , xorg and
xfce ~x86, gentoo 2.6.30 with KMS, anymore.
  Both kernel and X switch to 1280x800 resolution automatically, xinerama is
disable.

When I connect a external monitor, I just use this basic script to adjust my
external monitor to have a wide screen (VGA1)

xrandr --output LVDS1 --mode 1280x800
xrandr --output VGA1 --mode 1280x1024 --above LVDS1

To do this more useful, you can pass the resolution of VGA1 as a parameter.

To disable wide screen :

xrandr --output LVDS --mode 1280x800
xrandr --output VGA --mode 1024x1024 --same-as LVDS
