The "normal" host driver would be i915, you'd get reduced performance
and functionality from anything else and non-pci drivers might be even
worse than i915 about dynamic binding.  You don't need to blacklist
i915 to be able to unbind it for vfio use, but as I recall, i915
doesn't always like to re-bind to the device so you might need to file
some upstream bugs against i915 to get those fixed.  Thanks,
