I just tried this on a random platform that I have around, and do not see this problem. But also, what exactly is your end-goal here? While one can modify the fdt in memory and even modify the bootargs passed via this method, normally one will just set bootargs in the environment and let the fdt be updated by the normal mechanism (which will I suspect blow away your modifications unless bootargs is _not_ set in the environment).
