I'm not sure about that, the page doesn't list what happens if an LGPL project uses some parts of a BSD project. The decoder was started from scratch and the parts which were taken from libdaala (DCTs, PVQ and the entropy decoder) have had major modifications done to them. So I still think it's fine to just state the Xiph copyright and use only the LGPL license.
I found this page which states that I'm allowed to do this: http://lucumr.pocoo.org/2009/2/12/are-you-sure-you-want-to-use-gpl/ And it does make sense, the license says to always keep the copyright but does not say to retain the BSD license nor what would happen should major modifications be done to it. Hence why it's GPL compatible.
