I've run into this often. Two alternatives to the problem are to either fill the space with non-combustible isolation of seal the combustible material with a noncombustible surface. If done correctly it's no worse (fire wise) than continuing sheetrock on woods studs and encapsulating them where they penetrate a drop ceiling into an otherwise non-combustible space. At worst you seal up a pesky worker (preferably a taper) under the stairs. And you won't need a cask of Amontillado to lure him in. A Bud Light will probably suffice.
