Yes this is "normal". X tries to bind to the PCI with the lowest ID, in our
case 9600M has ID=2 and 9400M has ID=3. So you will have to use BusID:

Section "Device"
    Identifier  "NOUVEAU"
    Driver      "nouveau"
    BusID       "PCI:03:00:0"
    Screen      0
EndSection

Now if you are screening the 9400m, X should start without problem.

BR.
