Kernal Panic... clues?

Question

I was just installing and testing some RAM on my brothers G4 PowerBook and I got a kernal panic. After rebooting I was pulling up the system preferences and got another one.
I can't tell from the panic log what's going on, maybe someone here has a clue for me.

Unsure - just look at this checklist to make sure you have not missed one of the easy & common causes... but you have probably done all of that!
- +AHT should be on the system disk that came with the PBG4 17inch...+.
Never heard of a dmg for that...
"Getting frequent Kernel Panics? Here is a short list of good troubleshooting steps from The X Lab website:
1. Repair disk and permissions with Apple's Disk Utility. Start off by *repairing disk permissions*. If that doesn't help, restart from an external Firewire drive or the Mac OS X install disc to *perform a full disk repair on your boot drive*.
2. Rule out major hardware problems. Run the *Apple Hardware Test* _that came with your Mac_. Be sure to test for defective RAM which is a leading cause of Kernel Panics."
_http://docs.info.apple.com/article.html?artnum=86287_
"Running the Apple Hardware Test in Loop Mode overnight is an excellent troubleshooting step for finding intermittent hardware problems. It is especially useful when troubleshooting intermittent kernel panics.
If Loop Mode is supported by the version of the Apple Hardware Test you are using, you run the Extended Test in Loop Mode by pressing Control-L before starting the test. Looping On should appear in the right window. Then click the Extended Test button.
The test will run continuously until a problem is found. If a problem is found, the test will cease to loop, indicating the problem it found. If the test fails, be sure to write down the exact message associated with the failure.
We have read of cases where RAM problems did not show up until nearly 40 loops, so give it a good run."
"3. Confirm you have sufficient RAM and disk space. As a rule of thumb try to have at least 5GB of disk space on your Mac OS X boot drive, and 512MB or more installed RAM.
4. *Restart in Safe Mode*. Hold down the Shift key immediately after you hear your Mac's startup chime. You should see the words "Safe Boot" in the startup screen. If a Safe Boot resolves the Kernel Panic, this implies a Startup Item or Login Item may be the cause.
5. Disconnect all external devices. Try disconnecting everything except an Apple mouse, keyboard, and the monitor. Do the problems go away? Start troubleshooting devices and drivers.
If these steps fail to resolve the problem you may need to reinstall Mac OS X or get additional help from an experienced Macintosh technician..."
