You might also try, in nouveau_accel_init:

    if (device->chipset == 0x96)
        return;

It works without nouveau.noaccel=1 and has no scrambled screen (at least for
the GUI and the console, except for a tiny moment of full garbage (boot logo?)
but it gets cleared away after), but it is unstable (hanged up some times at
boot) and it spams a lot (more than 1600 lines) of

Strangely, when connecting an external monitor to the laptop (MacBook Pro mid
2009, same cards), the GUI isn't scrambled any more and the console still is,
but in a "better way".


I'll try to find why with an external monitor or with acceleration on the 9400,
the handover goes well.
