Spontaneous logout in Snow Leopard

Looking for anyone who has experienced the blue screen and logout issue with Leopard or Snow Leopard and who has resolved the issue.

I have been having this problem with my Macbook Pro 3,1 since Snow Leopard first came out. I have seen the variety of discussions and it appears that Rosetta is the problem for some people, while 10.6.2 fixed the issue for others, but it appears that the problem remains for many. As of 10.6.7, this problem still exists on my machine. I do not have Rosetta installed. It happens when plugged in or unplugged, with an external monitor or without, with USB attached and without. There appears to be no rhyme or reason to it. It will happen 10 times in a day, sometimes while the machine is not being touched. I can go a month without it happening, and then pop back up when I least expect it.

Apple has looked at my crash logs but has not offered any real solution. While I appreciate their willingness to look at the logs, it is strange to me that the logs cannot point specifically to what is causing the problem.

So, has anyone solved this problem or heard any updates?
