I have read both articles, essentially Hawass puts forward the idea that G1-d was a changing room for the king during the sed festival, but uses Djoser's southern mastaba as parallel, skips over all that came before Khufu, like his father and validates it by stating Khufu's pyramid complex was experimental. It's interesting that he writes the King would enter the >>>burial<<< chamber of G1-d to change his clothes, if it were a tomb maybe, but he's proposing it was built as a changing room not a tomb. Not a shred of evidence supports anything he suggests for its purpose and/or function exists. G1-d is not symmetrical in shape or placement relative to all other pyramids at Giza, contradicting Hawass' own statement that Old Kingdom builders preferred symmetry.
Just like the so-called Trial-Passage found outside Khufu's pyramid there is no way to determine if G1-d... 1. belonged to an earlier pyramid (doubtful) 2. was an after thought of Khufu's builder 3. was a tomb 4. or as Hawass claims that it was a changing room. Again my personal thoughts are that G1-d was built as a non-royal tomb or a chapel for offerings long after Khufu's reign. The craftsmanship of the construct, the materials used indicate that G1-d was not built during the Old Kingdom.
