Following your hint I now created this:

  Section "Monitor"
          Identifier      "LVDS Monitor"
          Option          "DPMS"
  EndSection
  Section "Monitor"
          Identifier      "VGA Monitor"
          Option          "DPMS"
  EndSection
  Section "Monitor"
          Identifier      "S-Video Monitor"
          Option          "DPMS"
          Option          "Enable" "0"
  EndSection
  Section "Monitor"
          Identifier      "DVI Monitor"
          Option          "DPMS"
          Option          "Enable" "0"
  EndSection

... and attached these monitors to the Device:

  Option          "Monitor-LVDS"                  "LVDS Monitor"
  Option          "Monitor-VGA-0"                 "VGA Monitor"
  Option          "Monitor-S-video"               "S-Video Monitor"
  Option          "Monitor-DVI-0"                 "DVI-0 Monitor"

... and verified in the Xorg.0.log that the assignment works properly:

  (II) RADEON(0): Output VGA-0 using monitor section VGA Monitor
  (II) RADEON(0): I2C bus "VGA_DDC" initialized.
  (II) RADEON(0): Output DVI-0 has no monitor section
  (II) RADEON(0): I2C bus "DVI_DDC" initialized.
  (II) RADEON(0): DFP table revision: 4
  (II) RADEON(0): Output LVDS using monitor section LVDS Monitor
  (II) RADEON(0): Panel ID string: Samsung LTN150P1-L02    
  (II) RADEON(0): Panel Size from BIOS: 1400x1050
  (II) RADEON(0): BIOS provided dividers will be used.
  (II) RADEON(0): Output S-video using monitor section S-Video Monitor
  (**) RADEON(0): Option "Enable" "0"
  (II) RADEON(0): Default TV standard: NTSC
  (II) RADEON(0): TV standards supported by chip: NTSC PAL NTSC-J 
  (II) RADEON(0): Port0:

Still it doesn't work and I get the embedded screen on startup. And still my
VGA output is silent. :-( 

Any other hints?
