New iBook, kernel panics when awakened from sleep

Question

I've been going nuts for several weeks now due to issues with my new iBook G4. When it is not plugged in, it may be fine when it wakes from sleep, or else it may wake to a black screen of death or else wake up and then freeze (requiring a restart) a few seconds after waking up.
I've reset the PMU several times, removed the third-party RAM (which I thought resolved the issue, until two crashes today when waking up unplugged), reset the PRAM, ran Disk Utility, did an archive and install of 10.4.2, etc. For a day, it would also go through infinite wake/sleep cycles when plugged in with the lid closed, but it resolved on its own within 24 hours. I was all set to send it in to Apple when the issue resolved itself on its own.
But I'm stumped as to the nature of the kernel panics/freezes, etc. They only happen when the iBook is unplugged from AC, USB, etc. and it is not 100% predictable. It may happen the second time I'm waking it up after not being connected to anything. Or it may be fine.
Here's the panic log from today, the details of which are identical to the panic that happened an hour earlier:

Suggestions? Is this really a hardware issue relating to the AirPort card, or is it something related to kernel extensions? It does not appear to be a user folder-related issue (I tested that as well). Thanks!

Answer 1

I've been having similar problems with my iBook G4/1GHz computer. I haven't yet figured it out when or why it crashes after sleep, but this is sure: everytime there is USB mouse connected, it does that crashing. I bought mighty mouse to make sure, it wasn't the mouse which caused the problems. But no, it wasn't the mouse.
I've tried to google some solutions, but haven't found any. This is very annoying problem. Anyway I can get that crashlog after reboot?
Symptons:
When lid is opened, fan's are started, but no picture or network connection or anything is alive. Display is black. Requires reboot to get it up and running again.
I have run hardware tests on processor, usb, video ram and ram and all have passed.
