You install Chameleon on a certain drive. On that same drive there should be a folder called Extra. In that folder there can be a folder called Extensions and a file called Extensions.mkext, or both. In the first you can put .kext files (which are really folders containing the files of an extension). The .mkext (multiple kext) is a cache of various (or I guess it could be just one) kext that makes the time needed to load them less.
I don't know of any one with sleep, when I get my new board I'll see about getting that going.
