Any chance of getting EID_root_key?

Hi, i have damaged my cpu on a 80gb ps3 during deliding... I got a 60gb now and i really want to get my saves from the old hdd... I have the original dump i used to cfw the 80gb and i also have access to SysCon... Is there by any chance a way to get the key so i can decrypt the old hdd? The system no longer boots and most likely never will again so there's now way to get the key that way... Is there a way no matter how hard it is?

Thanks in advance
