Two Kernel Panics in three days; log included; please help?

Hey everyone...I've gotten two kernal panics in the past three days. I copied the report before sending it to Apple, and I was hoping someone might could look at it and tell me what went wrong...

Thanks in advance.

Wonderful. What I feared. Thanks for doing the legwork on that. I do have 3rd party RAM. I'll have to look into replacing it...thanks for the tips on the hardware check.
