I've just pulled my duemilanove board out of storage, and it works fine through USB. However, when I plug it in via the barrel jack, the PWR light just flickers dimly, and refuses to work. I've tried with several different wall-plugs, and now I'm stumped. Could anyone help me out?

Power Problems?

Thank you. Just one more question: Could any 5v voltage regulator work?
I.E one like this:
