Humm, I'd prefer if you wouldn't create such symlinks, as it suggests
those devices would actually be full VT devices, but they aren't, they
speak a different $TERM and have no matching /dev/vcsa stuff and don't
speak the ioctls....

Yeah, I am pretty sure that's what we should do. I figure I should hack
that up. I'll work on it now.
