@yifanlu: I guess you can extract the latest default kernel from the official update file, if you haven't got a backup.
As for the packer, the shell script don't need to have a specific name, AFAICT, the update tool run *every* sh file in the binfile, sequentially (ie. 0000-patches.sh, then 5555-kernel.sh).
@zetareticuli: Also, unless you're using a custom SIM, that would, again, break Amazon's terms, because you're hijacking the 3G connexion. And, btw, you don't need to touch the kernel to do 'virtual' (userland) mounts, Fuse is installed (and used by Amazon).
