    can you provide the output of the X server that should stand around
    /var/log/XFree86.0.log or alike ?
    from reading it we'll probably learn why the 1280x1024 resolution was
    pushed out of the available list.

    also, if you can, try switching to external screen _before_ X11/Xorg
    starts. maybe you'll get some other monitor detection by the server and
    thus get more video modes available. please provide the X server log
    when starting with the external screen already switched, it might be
    different from the previous one with built-in lcd screen.
