Thanks. I''m sure this is fine (or at least, I will be when someone
acks it) but it really could do with some explanation of why it''s
right - in terms of the code changes, rather than just "makes some
particular chip work".
Ian.

Actually those are changes to please the driver more than the chip itself.
