Finally finished Sunne in Splendour and can certainly see how the events could have inspired GRRM for ASoFaI - maybe even this book itself.
There's the familiar use of similar names, ie, Ned and Dickon. And towards the end, the whole Edward IV/Elizabeth/Richard III thing going on seems so totally Robert Baratheon/Cersei Lannister/Eddard Stark.
ADDED: And review up here:
