PSA: There is an edit button, so in the future, if you post something and go "aw crap, I should've remembered to add [insert thing here]!" - you have a way out without double-posting. I know I've done that before - it happens to the best of us! At least this isn't Twitter or something, right? :P
I am inclined to agree with pretty much all your conclusions on efficiency analysis - the tables are pretty much only good for human sanity when developing without an IDE or similar. Having to search & replace for address changes is an absolute pain. I don't have much in the way of comments beyond that - brain is a bit numb from it being late where I am, and from programming a kernel for the past several hours. Will re-read everything in the morning when I'm less zombified. >.<
