It has already been hacked. Basically a voltage drop across 2 pins IIRC.
EDIT: More than 2 pins, actually. According this guide http://pinouts.ru/PortableDevices/ipod_pinout.shtml, depending on the type of device you want to emulate(charger, stereo dock, etc.) you'll need to either short or drop the voltage on different pins.
The way to hack in a charger against the "this charger not supported" has been known a while.
I'm talking about the data connection on the iPod/iPhone docking connector. You can't access the dock API unless you're an approved Apple "Made for iPod" vendor and purchase special chips from Apple that handshake between your docking peripheral and the device.
Hacking power is one thing, but it's useless unless you can move data in and out of the device. Using the headphone jack to move data with FSK is clever but slow and not very robust.
