6362 (NAND rev 2.1, ann. Sep 8, 2009), 6368 (v0.1?!?, ann. Jan 7,
2009) and 6328 (v2.1, can't find release date) are earlier chips that
have an identical combined interrupt enable + status register and a
NAND controller within the same 32-bits word, so these would qualify
as a better compatible string for this specific addition integration
stub here. I would gowith 6368 here then?
