I don't know for the patch ( not tested yet ), but along with CEVA's tips, i add to edit edit.php where CKEditor is attached to the text area. It kept stripping html tags 
So i added :
{...}
var editor = CKEDITOR.replace( 'post-content', {
skin : 'moono',
allowedContent: true,
forcePasteAsPlainText : true,
{...}
Seems to fix it.
