I'm no expert on this but I was trying to understand more about the IBM eFUSE and how it works and I came across an xbox 360 cpu datasheet with the eFUSE pinouts. I was thinking about how when you install 8948 and it blows eFUSES or if you have an updated CB and it would blow the eFUSES, would it be possible to take the efuse enable and the efuse vcc pinouts and wire them to a modchip and cut the tracks for the efuses and rewire them so you could send back a different signal and boot an older kernel? Would something of the sort be possible? Why or why not?

Thanks,
bifnewman
