A highlight from the comments:

>> That was Captain Ahab level persistence. I wonder how long it took him.

After slowly reading this with inquisitiveness and looking up a lot of things, I'm really curious to know the years / level of low level systems programming and experience that this kind of debugging and write up takes. I am humbled by the knowledge of the OP, and deem myself not worthy!

Someone should publish a book of these stories. I would buy it.
