Just a warning that I would not put two Tantalums back to back as they are much less tolerant of reverse voltage than Aluminum electrolytic capacitors. I really think, VG, that you should be able to do what you want very well with high-ish value ceramic capacitors (say 10uF) and a high value resistor as a load, making the R*C product several seconds long.
