Kernelcache

The kernelcache is basically the kernel itself as well as all of its extensions (AppleImage3NORAccess, IOAESAccelerator, IOPKEAccelerator, etc.) into one file, then packed/encrypted in an IMG3 (iOS 2.0 and above) or 8900 (iOS 1.0 through 1.1.4) container.

The joker tool, from http://newosxbook.com/ can be used to dump information from a decrypted kernelcache - including system call and Mach trap addresses (in the kernel) as well as a list of all the KEXTs contained therein and their load addresses. The output from a 6.1.3 kernelcache (iPod 4,1) is as follows:
