You're right - my bad.  That was an error in editing my email :P

 mkinitcpio is already including the vfio modules by default?


I didn't add this because it's assumed in the guide that you'd be adding
the vfio modules to mkinitcpio.conf anyway - kind of redundant.  For the
sake of being thorough, you would need to add *MODULES="vfio vfio-pci"*
