Hi,
It looks like you are not booting from the 3.18.16 kernel.
If you have installed the packages, you need to create an entry for the
new kernel by editing /etc/yaboot.conf and once saved run ybin -v.
Also, i have built a 4.3.0 kernel deb package.
Aside from the newer kernel, it also has a nouveau pageflip patch for
drm and pre nv50 class gpu's.
Also, it has i2c-powermac built in to the kernel, so it should
automatically start the appropriate windfarm driver for fans / cooling
and snd-aoa sound driver for your machine.
MSI interrupts are enabled again in this kernel, but still wont work
with nouveau and powermac 11.2 for now
Once installing the kernel and modifying yaboot, you need to create a
module option file in /etc/modprobe.d and save file as nouveau.conf with
the following single line below:
options nouveau config="NvMSI=0"
Once file is saved, you need to update your initrd for kernel 4.3.0,
apply the change by running the following command:
update-initramfs -u
Reboot and if all goes well, you should be booting with kernel 4.3.0 and
lightdm login should pop up.
Up to you, but If you switch to sid repositories, mesa 11.0.5 is
available and you should be able to get OpenGL working with nouveau and
your particular GPU.

Please let me know how you go.
