Or even easier (if you know how to use dd, view /test/firmware-tools/flash-kernel-1.sh (or something), get the offsets, and use dd from SSH.
Yeah everything could have been really easy if I hadn't busted my Kindle

I fiddled with the root filesystem until all of a sudden my Kindle wouldn't boot any more. Since there are no firmware updates for the DXG out yet, all I could do was get the uImage from U-Boot directly.

I modified the initramfs a bit in order to mount a filesystem image on the large 3Gb USB-accessible partition and was able to get a regular Debian Linux to run, but I will blog about that later when everything is up and running.
