Hm, I'm not really sure about this, but I think the boot loader is in charge for doing at least a minimal bit of screen setup, and since the serial connection would require a working boot loader, you *might* be screwed (or rather, the screen).

What USB device do you see when it is connected? A mass storage device? Can you get the USB ID? What I would like is to verify if it functions "normally" (just without a screen).

As for hacking the Kindle 3 in a nutshell: Jailbreaks exist for all firmware versions. They allow to put your own software on the device. USB network is something you want in order to access all the file system (plus execute commands on the Kindle, but there are other means like terminals - myts - or launchers like launchpad and even graphical ones). With a serial connection you can set up the boot loader to export the full eMMC of the Kindle, allowing to re-flash the root partition and kernel (actually, I'm not sure if you can recover from a malfunctioning kernel this way, maybe the rescue system is an initramfs for a running Linux kernel).
