I thought these commands would prevent the loading of nouveau from
initrd/initram.

Try booting into mode 3 or mode 1 and see if the nouveau driver has been
loaded (lsmod | grep nouveau). BTW you need both the nouveau.modeset=0
setting *and* the blacklisting at modprobe level, e.g. nouveau needs
blacklisting at two levels.

I have the above kernel command line option and blacklist nouveau
in /etc/modprobe.d/nvidia.conf and didn't have a nouveau/nvidia clash
since ever.
