It would be great if the guy you were talking to did follow through on this. I just had another kernel panic and sent it to Apple with a short description of what I believe to be the problem (kexts making the graphics card run too hot in SL/ML). I also sent a link to this thread and alerted them to the fact that there is a collection of evidence here, from panic logs to screengrabs and video. I guess I need to feel like I'm doing something!
Do you think your new logic board will have the ATI card? I would imagine that getting a logic board that has the same graphics chip will have you going around in circles unless they do something to sort the core problem.
For the sake of completeness of information, here is the latest kernel panic. Admittedly I had ok uptime* on the iMac since upping the revs on SMCFanControl, but I worry that I'll just need to keep upping those revs to achieve stability.
*When I say 'ok uptime' I had one kernel panic in the first 3 years of having this machine so it's not any great achievement that 'ok uptime' now means a couple of weeks without a panic.
