I think what xmguy is saying is he wants a "pure" stock rooted 2.2. In other words, 2.2 stock, and just push superuser and su to it like "pure" 2.1. Might be no difference, but still, I believe that's what he's wanting.
Yup thats what he means. Thats actually what i did with 2.1. I just put sprecovery and then with that, added superuser and su to my stock 2.1 (and then switched the kernel for oc'ing). Thats kinda what i wanna do with 2.2, just allow the ota update to come in so that i'd be totally stock and then just add the update.zip to add the root access.
