Hi Airmann,
I would say it would do an autoland.
The list of "Required Equipment for CAT2 and CAT3" (QRH) doesn't include a requirement for the ILS to be loaded using using the data base.
However I never imagined that a bit of software which got very upset if a fix radial crossed the final approach just before the runway would cause the FMGCs to crash either. (old OEB169)
