(Fujitsu Siemens Amilo Pro 2030 Notebook)

in xorg.conf:

Section "Device"
        Identifier "Standardgrafikkarte"
        Driver "vesa"
        BusID "PCI:1:0:0"
EndSection

   DefaultDepth 24
  ...
        SubSection "Display"
                Depth 24
                Modes "1600x1200" "(pitch" "1600)"
        EndSubSection

so obviosly the coice from boot was ignored.
