You have to place a file with the name "reginfo" in "/var/local/java/prefs/" (same method as for k2 and k3 i think, but the format of the file differs).
Here a modified example of the "reginfo" file i used today to register my kindle touch (Fw: 5.1.0):
Nice finding... but this will only work as long as you never turn on WLAN. As soon as you turn Wireless on, your device is unregistered again, and you end up with a device that has collections to which you can't add items anymore.
