Kernel Panic at Startup w/ External Display

Question

After updating to 10.5.2, whenever I boot with my external display and my MBP lid down, it will kernel panic and make me shut down by holding the power button down. That never happened before 10.5.2.
However, it will work if I boot with the MBP lid open. Then once I'm all booted up, I shut the MBP lid and it goes to sleep. And then I just wake the computer w/ keyboard and it works.
But that's such a PAIN in the a$$...............
Any insight would be appreciated. Thanks!
P.S. I have ALL updates, I've also done a repair permissions too.

This article explains what Kernal Panics are:

This one shows you how to troubleshoot your OS:

Kernal Panics at start up are most of the time a software issue so you may have to reinstall your OS.
You can try an Archive and Install first as shown in this article.

If that doesn't work then you'll need to do an Erase and Install as show in this article:

If you are uncomfortable doing so then make an appointment at your local apple store at www.apple.com/retail for the Genius Bar.
Also if you purchased Applecare with your computer you can also call AppleCare at 1800-APL-CARE and they can trouble shoot over the phone.
Good luck!.
