Can anyone interpret my kernel panic?

[gafferbee]

Hi all. I posted a week or so ago about my misbehaving iBoook G3.

Earlier today I left it in what I thought was sleep mode, but when I came back to it just now it was all frozen, with a big grey transparent box in the screen, a power button logo visible behind it, and a message telling me i need to reboot.

From reading previous posts i understand this is a kernel panic. I checked the panic log, which is below. Can anyone who understands these things shed some light on this? FYI, I had a logic board replaced about Easter time, and things ain't been the same since.

Thanks.

Kernal panic's in my experience have usually come from bad RAM run a hardware test on your iBook to see where the problem is...

That, or extremely poorly written programs. Even though OSX is crash-proof by design, software can still bring on kernel panics. Bad RAM most likely though.
