We should start a project. We would take all of the files from a new PSP dump and attempt to map out the functions/purposes of each of them. This would make it a whole lot easier to attempt hacking on the firmwares. We may even uncover the homebrew patches and find a way to flash the old files into newer firmwares (I know, impossible on 2.01>). We already know a lot about them just from the file names--but we could go even farther by figuring out the other ones.
