The servos I'm using are rated 5V @ 50mA. I don't know why they wont work when each pin should be 1 amp..
I thought I read that the Arduino pins were 1 amp. Huh. Ok well here's the link: http://www.vexrobotics.com/products/accessories/motion/276-2163.html It should be on there. I found it once, and I can't find it now. I did have it working before on a 9V. That was a while ago though.
