Slic3r 0.71 has a drop down menu in the "print settings" tab to specify whether support material is extruded with the "primary" or "secondary" tool.
I haven't actually tried this since I only have a single extruder on my Prusa Medel. But it certainly looks like the software is intended to support a dual extruder setup where the second extruder is used for support material (presumably water soluable PVA).
