I've animated airborne dust as little wadded up strands and it looks pretty cool. For rotation I took the center of the bounding box of the wadded up strands as a point around which I would rotate both the particle and strand as a post-simulation effect (similar to the recent tutorial on my site andy.moonbase.net).
I didn't have to worry about collisions between particles and was able to get away with simple spherical collisions for the dust in general, which could happen in the simulation tree, so it was easy in that sense. Haven't looked at the falling leaves compound in ages but I suspect you could hack into it and isolate out the bits you need, if I remember right you might even be able to simply put the leaf falling motion on the simulated particle just as I put a "spin particle" node on in the tutorial. But if you just want a straight fiber and to use the falling leaf compound, an instance would be simple and direct, as Alan suggests.
