I have a question - If I have access to the serial port, is my kindle basically unbrickable? I ask this because I am doing all sorts of flashing to try to get android to boot and I don't want to toast my device.
Network boot the experimental kernel and use a network mounted file system.
No other method is safe on an embedded device.
With the serial port connection - you should be able to do the above using u-boot - - either the installed one or a modified one.
