Some progress, got nowhere on Windows, so decided to recompile the kindle fastboot executeable on a Raspberry Pi and to my great surprise they are talking. Not very informative as conversations go :
fastboot devices returns - a string of ????????????
fastboot getvar bootmode returns - FAILED (remote: Variable not implemented)
however at the same time the serial bus console displays - WARNING :unknown variable: bootmode (same result with getvar serial)
however
fastboot reboot - reboots the kindle.

Is there someway I can test this implementation of fastboot by writing data to the kindle without risking overwriting something important, and ultimately when I do have to write something important , what do I need to write (the developer key would be good) and where to ?
