Nevermind, I figured out what you were really asking.   I have never seen a
scenario (CONFIG_EMBEDDED or otherwise) where the full parameters were not
available via /proc/cmdline.  I'm guessing that means there isn't currently
a way to get them out of memory.

If anything, the linux-tiny guys might have a config option to do that.
