You need a USB host bridge device, such as a small microcontroller with USB host mode. The kindle will see it as a host PC. It can tunnel any kind of traffic over the USB connection between the kindle and the I/O pins provided by the microcontroller.

Up until recently, USB host mode was complex and usually needed a special USB chip to support it, but recently a full USB host mode software stack (LUFA) for embedded devices was open-sourced and has been ported to ARM and AVR devices.

Another option is the Kindle 3, which has an external serial port that could easily be connected to almost any little embedded processor (such as the $4.30) TI 4-3-Oh device.
