Well, there are lots of things broken in the current implementation.
Just take a look at how the cn_term is entirely commented out, only
because syscons can't handle it.

The only thing I tried to do with those changes, is remove dead code.
If someone comes up with patches to properly restore these features, I'd
be more than happy to commit them to SVN.
