Constant kernel panics since upgrade to 10.4.4. help!

Question

Well ive just spent the past 3 hours trying to figure out exactly what went wrong with my iBook, but it was Kernel Panicing like crazy. I couldnt even get online long enough to make a post about it.
Lets recap.
I updated to 10.4.4
Several hours later the Mac crashes for the first time since I switched 3 months ago.
It crashes again.
Kernel panic!
More kernel panics!
So as soon as I logged in, I created a dummy account then rebooted with it. The dummy account would crash too so I knew that it was a system problem. This leads me to believe it was 10.4.4
I did an archive and install.
No luck
Any thoughts? I have not installed any hardware. Its as it was prebuilt. It cant be a hardware problem.
I installed shapeshifter several weeks ago and uninstalled it about 4 days ago.
I did repair permissions after updating.
Here is the crash report:

Answer 1

The kernel panic points to Airport. Either your Airport software is way out of date or your Airport card may not be properly seated or has failed. So the first thing to do is remove the Airport card. If the panics cease, then reinstall the Airport card and see what happens. If it panics again, then remove the Airport card.
The next thing I would do is:
Boot from your OS X Installer. Be sure to use the installer for the version of OS X you have installed. After the installer loads select Disk Utility from the Installer menu (or Utilities menu if using Tiger.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The next thing I would do is download the 10.4.4 Combo Updater and reinstall the update. Then reinstall the Airport card and see if it works properly.
I would suggest that before installing the update that you first boot into safe mode.
