The K5 is very, very, very, very hard to permanently brick, as we can put it in downloader / fastboot mode or whatever it's actually called (see Kubrick) .
And @yifanlu very clearly told us what happens when we try to recompile something that low-level on the Kindle ...

So, @NiLuJe and @knc1, it looks like the first step seems to be a download and extraction of the stock Paperwhite 1 firmware to see what kernel version it runs.
An easy way would be by cracking rootfs open and seeing what's the name of the folder under /lib/modules/. If for some reason that doesn't work, then it could be checked via extraction of uImage.
What do you think?
