Eric,
That shouldn't be any different than installing paneling over drywall, which is not a problem.
The main thing is that there is gypsum board there, however ... you do not know what type is on the ceiling - 5/8" Type X? Just do not know unless you can see it from up in the attic (at least he has a pull down stair for you to check it out) - of course, though, depending on the arrangement of the ceiling / floor joists for the living space above, that stair might now need to be covered with 5/8" Type X drywall, or, they could install 1/2" drywall on the attic side of the living space wall up in that attic.
The main thing is to get the separation between the garage and the attic right, and there are a couple of ways to do that.
