The display cable on a K3 is near the edge. I have successfully "borrowed" a screen from another kindle without removing it, but just removing the back covers and swapping the eink cable connection. With the kindles back-to-back, there is enough room to get in between them and plug in the cable with a needle-nosed pliers (or tweezers). You may be able to see what is on the eink display during startup that way... If you can turn on the voice guide in the settings menu, a kindle with a broken screen is quite usable...
You may also want to turn on USB networking all the time (using the AUTO file).
What firmware version are you running? Perhaps your version (and patch level) does not output to the serial port after the kernel loads...
