what exactly are you calling a vanilla installer? if your using my hack you have to run a myfix after installing kexts into e/e if not they will not be picked up while it builds the kernel cache.
yes i think it is very complicated as that would be piracy... and unless your paying for the lawyers to battle apple we will not provide that. go to your favorite torrent site and take a chance downloading crap just to be a cheap ass.
now for the second part of your query that is the point of the boot pack.
you might have to patch Aicpupm kext or back it up some where and delete it from S/L/E or try adding nullcpu kext. also the kernel might need patching. clover boot loader can do both if configured correctly.
yeah i usually have to disable the bt then re enable it. you might be able to do it trough the wifi switch if your bios has the option. i have a usb dongle and i pull it out then reinsert it.
Intel® Centrino® Advanced-N 6205 Is not supported by osx you need to replace it with a compatible wifi card.
