Comment # 4 on bug 51798 from

Slight improvement of Ilia's trick

grep . /sys/bus/pci/devices/*/drm/*/card*/{status,enabled}

I think so too,
* status indicates if there is a connection (cable is plugged)
* whereas enabled - if the output enabled/is there a user that has enabled

Indeed, I was wondering why nouveau is loaded only once by X

A minimal xorg.conf like the following should do the job

Section "Device"
    Identifier  "Device0"
    Driver      "nouveau"
    # Actual PCI location of first card/gpu
    BusID       "PCI:3:0:0"
EndSection

Section "Device"
    Identifier  "Device1"
    Driver      "nouveau"
    # Actual PCI location of second card/gpu
    BusID       "PCI:4:0:0"
EndSection

Additionally if you're planning to use three or more outputs you might want to
setup xinerama/zaphod heads [1]
