Have you looked at the patches I sent a while back?
They included a whole set of tidyups to make the code easier to read.
Unfortunately I rather overloaded Sarah at the time.
Another change I didn't get as far as coding was to cache the doorbell
address and value within the ring (I think they can't change), making
'ringing the bell' much faster.
