I followed the subsequent discussion on this, looks like most of you are 
booting your kernels with uBoot.
We are using linux_prep bootlets from freescale to boot linux kernel.

I have following options turned on in my setup
CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y

I am building imx28-evk.dtb and appending it to zImage as in:

make  imx28-evk.dtb
cat zImage imx28-evk.dtb > zImage_w_dtb

We will investigate this further and let you know what I find, would be 
glad to hear if anybody else is using MXS platform with appended device 
tree.
