I also wrote up a page discussing my fixes and experiences,
I just read through your link and it is fantastic! I am wondering though, does any of this matter with regards to the package that I choose? I am trying to fit this all onto a fairly small board so I probably won't use the pdip version of the 1284P. If I am feeling brave I may go for something as small as the QFN package as I have had a lot of success hand soldering a 4mmx4mm QFN10 package and I think I may be okay soldering something that is materially bigger than that.
