MD_ROOT examples?

Could someone point me to some examples for how to use MD_ROOT with 5.1 

What I am trying to do is create a system which:

1) Boots off of a hard drive
2) Copies a full filesystem into RAM (I've got lots)
3) Boots the kernel and mounts the RAM as its filesystem
4) Shuts down the hard drive completely

I've seen a few things for creating read-only systems, but I don't want to 
have to access the media after boot.

There are some references to the old MFS stuff, but I'm not finding any 
obvious references to doing similar stuff with MD.

Any pointers would be appreciated.
