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).
