For the rest: a very interesting read!
Btw.. your default system boots kinda slow without paralellisation..
My default boot is 56 seconds and that's with a fully updated Fedora 9 rawhide.
Breaking out the services that i don't need saves 5 seconds: 51 seconds boot.
And i expect to get atleast 10 seconds time boost with your script :)
(once i know where to place the files)
