textareas in CKEditor

It's a step up from TinyMCE, but there's a problem with CKEditor that I'm having: it destroys certain formatting. I'm not talking about adding paragraph-tags left and right, Take

<textarea>
Hey peter,
   what's happening? Yeah...
</textarea>

this becomes:

<p>
   <textarea>Hey peter, what&#39;s happening? Yeah...</textarea></p>

The problem here is that it removes line breaks, which are important in textarea elements. Is there a way to stop it from doing this?

I tried

config.protectedSource.push( /<textarea>[\s\S]*?<\/textarea>/g ); // textareas

However, this hides textareas from being displayed, which is undesirable.

edit: Here's the thing: CKEdit supports <pre>, so adding <textarea> support should be a triviality. Is there a bugtracker somewhere? I'd be willing to submit my own patch.
