           Summary: Xorg server does not properly autodetect dual nVidia
                    graphics cards

X.org log demonstrating the error

When starting the X server, it detects that there are "More than one possible
primary device found"

(!!) More than one possible primary device found

The X server will then attempt to invoke the VESA driver instead of the Nouveau
driver (this is on the Fedora 11 Nouveau Test Day LiveCD)

Ultimately it will fail with:
Fatal server error:
AddScreen/ScreenInit failed for driver 0


However, if I manually add the following to an xorg.conf file, it loads
correctly.
Section "Device"
        Identifier  "Videocard0"
        BusID       "PCI:3:0:0"
        Driver      "nouveau"
EndSection

Section "Device"
        Identifier      "Videocard1"
        BusID           "PCI:5:0:0"
        Driver          "nouveau"
EndSection


The correct behavior of the X server should be to automatically generate these
entries for each card.
