I had my first ever kernel panic. I ran TechTool Deluxe after restarting the machine, and 3 things came up as a Fail.

I recently upgraded to Snow Leopard, and I just installed the 4 G's of RAM this past weekend.

I can't imagine that would cause a kernel panic.

Most panics are caused by hardware issues. Can't tell exactly what happened in your case, without seeing the log.

Since you installed new memory - that's the best place to start. Pull it. Clean the slots and DIMMs. Reinstall it firmly. Be sure to be properly grounded when doing any hardware work!

The things that failed in the Tech Tool report are:
Format Check , which says that this test result most likely indicates an actual hardware problem, and to try backing up, reformatting, and replacing data and testing again. Directory Scan, which says that media defects cause this test to fail, and they recommend the above. Volume Structure, which it says can be a minor issue or indicative of a more serious problem.

Repair the disk volume with Disk Utility.

If you've installed AppleJack, then you can use it to run the repair, without needing to boot on something else (OS X DVD, external backup, etc).

I printed out the kernel panic report, but can't find it on the computer to copy/paste it here. Is there a segment of it that would be useful for me to type here? Or, where do I look for it to try and copy/paste it?

Use Console.app (It's in /Applications/Utilities/) to view all system type logs. View the log list; it will be in there.
