Has the CVM interprerter code been rolled into libjit?

I just started looking at DotGNU and this statement intrigued me:

"We first convert the CIL bytecode into a simpler instruction set for what 
we call the Converted Virtual Machine (CVM). The simpler CVM instructions 
are then executed using a high-performance   interpreter."

This makes a lot of sense to me because IL code was written specifically to 
be JIT'ed, unlike Java's Byte code. So it's inefficient to interpret IL code 
directly (like mono's mint).

I realize that this CVM interpreter is going to be much slower than the new 
JIT compiler, but this is still an interesting option that can make it 
easier to support a new platform. I'm thinking about a smaller embedded 
platform that doesn't have a ton of resources, so a lean interpreter sounds 
like a good choice.

Is the CVM still a viable model, or has it been super-ceded by libjit? I 
understand libjit can fallback to interpretation on a platform that doesn't 
have JIT support yet, but I'm fuzzy on the mechanics of this. Can the 
current C# compiler still generate CVM code as an option?
