I've created a file  /etc/X11/xorg.conf.d/10nouveau.conf ,
which reads as above (apart from the "options" line, which is omitted) ;
I use spaces, not tabs.  I've tried all  4  permutations
of "Card1" / "Card0" & "modesetting" / "nouveau".
I also tried naming it '99...' : there's a '20opengl.conf', which says :

  Section "Files"
        ModulePath "/usr/lib64/xorg/modules"
  EndSection

I've also recompiled  xorg-drivers , then  xorg-server :
the former now has the USE flag 'nouveau'.  I've rebooted between trials.

Every time, Nvidia starts :

  (**) ModulePath set to "/usr/lib64/xorg/modules"
  (II) The server relies on udev to provide the list of input devices.
   devices become available, reconfigure udev or disable AutoAddDevices.

Is 'udev' getting entangled in this at some point ?

Does anyone have any further advice ?  Thanks so far.
