I did manage to cobble things together, although this is by far the ugliest contraption I've ever done as an administrator. The app is a big graphical one, so I had to put in the /path/to/voodoo/glibc directory libstdc++, libgcc and half of the various libs that come with X. The app lives in its own bubble of FC3 bits and pieces, but it does work.
