Just keep on following the steps in the order described in the thread you linked to.
I actually tried to do exactly what you explain in the nice thead linked before, following the post #13 I got the uImage file from the imx60_wario directory after unpacking the last update file update_kindle_all_new_paperwhite_5.9.5.1.bin with the kindletool,

Code:
testsrvpc:~/Kindle/Update # ls -1
CREDITS

VERSION
fastboot
imx60_wario
kindletool
kindletool-v1.6.5-linux-i686.tar.gz

rootfs.img.gz.sig
uImage
update-payload.dat
update-payload.dat.sig
update_kindle_all_new_paperwhite_5.9.5.1.bin
testsrvpc:~/Kindle/Update #
And flashed it to the kernel partition with the command showed in the post #16:

Code:
testsrvpc:~/Kindle/Update # ./fastboot flash kernel uImage
downloading 'kernel'...
OKAY [  0.092s]

In the minicom interface I got the next log output:

Code:

After that I executed the command ./fastboot reboot but the device never rebooted by its own, I must unplug the USB cable and plug it again, after that the device access again to the uboot promp, not to the recovery menu like MAD mention in post #17.
