I've got Lawrence's dmesg output and nouveau is being loaded very early on:

[7.591930] [drm] Initialized drm 1.1.0 20060810
[7.613319] nouveau 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

I don't have confirmation from him that he's been able to check:
cat /etc/modprobe.d/blacklist-nouveau.conf

has the 'blacklist nouveau' line and successfully run:
dracut -f /boot/initramfs-$(uname -r).img $(uname -r)

If he has done these then does anyone know how nouveau could still get
loaded? The next step would be to add nouveau as a rdblacklist line in
the kernel arguments, it looks like this is now done via
GRUB_CMDLINE_LINUX in /etc/default/grub.
