I read through Tygar and Yee's paper on secure boot during my research. Their work was very good to be frank. They foresaw most of the recent developments in TPM design, which I thought was quite impressive.
Oh - cool. It wasn't clear to me from your top-level comment how far back you'd gone. Even though it's old, I still think it's pretty good, and thought you should be made aware if you weren't already. Good to see that you're "on it"!
