How can I load items from a SharePoint list using its InternalName? As far as I know I can get it using either Id or Title like the following:
var clientContext = new SP.ClientContext('/News/');
var web = clientContext.get_web();
var list = web.get_lists().getById("{1DBA9283-0AFA-4FA1-9BBA-70D8D190971F}");
...
no the CSOM only offers methods to query lists by it's Id or Title.

The SharePoint List Schema doesn't offer InternalNames at the moment. See the Schema description http://msdn.microsoft.com/en-us/library/ms415091.aspx
