I suppose that in Kindle Touch u-boot is in serial flash chip shown by "Cracking open ..." article. I've made full dump of MMC (/dev/mmcblk0) and didn't found any traces of u-boot. But dump file is of 3959422976 bytes long, so it isn't exactly 4G, so it leaves Yifan Lu's theory possibly valid (maybe part of MMC where u-boot is located is hidden from Linux kernel). But, on other side, there is low-level eMMC initialization code in u-boot sources of KT, so it looks like u-boot is loaded not from eMMC...
