I believe the correct format is:

rd.driver.blacklist=nouveau

At some point in the past, I think the location for blacklist files 
changed to /usr/lib/modprobe.d/ and there was a bug in dracut which 
means the old location wasn't being picked up, so if the driver isn't 
being blacklisted in the initramfs then this could be the cause.

The other obvious question is does the NVIDIA installer update the 
initramfs after installation?

Check your raminitfs to make sure nouveau is being blacklisted:

lsinitrd -k $(uname -r) | grep nvidia-installer-disable-nouveau.conf

If not, try running:

dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

and check again.

If that still doesn't work, see my comment above about the location of 
the blacklist file.
