I can't help with a link, but I can agree with you on the difficulty to unlock the "green" one. I've tried 3 times and none have worked. I tried twice with the conductive grease and once with the defogger kit. I never was able to change the multiplier and on the last attempt, the only way it would boot, actually not boot, it would come up as 866mhz which is 133x6.5. It would detect it, then tell me the cpu was set wrong and needed to change it. My brown, non agoia, unlocked no problems.
