Hmmm thought as much, I don't pretend to know how doing this would be possible, just speculating. Getting to the data inside the CPU is really the holy grail of 360 hacking.
Free60 project seems to be at a complete standstill as far as I can tell. To me it makes sense to store the bulkier parts of bootcode inside the TSOP, encrypted with the per Xbox key, decrypting it inside the processor, no external signals to probe. I'm not really sure what's involved with the booting of the 360 (specifically how much space that would take up) but I remember space was a critical issue for boot code in the previous Xbox (leading to most of the mistakes) so to me it sounds likely that they only put the really secure things inside the processor, the rest would have to be in another chip, the ATI chip already has a load of stuff to do anyway, so TSOP seems plausible to me. Although thinking from a security point of view, if it couldn't be fit in the processor the ATI chip is the best place for it, the bus speeds are too high for most equipment to probe.
Where are you getting your information from btw? If Free60 is a slightly "tainted" source I better not base all my understanding from the information there. I tend to stay away from forums because they get so bogged down with rubbish.
thats what they thought about the xbox1 then a new lsa came out that was faster, another point to note they designed the XCPU from the ground up with IBM meaning the bootstrap could have the space tailered to it.
as for my sources, well they are secret and the information is not easily accessable on the net

, well not at all unless you hack my protected storage
