Thanks, but that's not an option. We definitely want to make use of
xorg.conf.d. :-)

Thanks. For now one could generate Screen/Device/Serverlayout snippets in
xorg.conf.d depending on the available hardware, e.g. for ATI:

/etc/X11/xorg.conf.d/99-devices.conf

        Identifier      "Builtin Default fglrx Device 0"

        Device  "Builtin Default fglrx Device 0"

        Device  "Builtin Default vesa Device 0"
EndSection
Section "ServerLayout"
        Identifier      "Builtin Default Layout"
        Screen  "Builtin Default fglrx Screen 0"
        Screen  "Builtin Default radeonhd Screen 0"
        Screen  "Builtin Default ati Screen 0"
        Screen  "Builtin Default fbdev Screen 0"
        Screen  "Builtin Default vesa Screen 0"
EndSection
