This may sound stupid, but I'm slightly confused and have a couple of questions.

Do you have to install the version of power kernel included in the file or can you stick with the latest (v46) version already available in the repos.

Do you have to install some sort of bootloader. I have used multiboot in the past and ended up having to reflash my N900.

Finally, can I still use the other features in v46 power kernel (usb host mode particularly)

Once I've been reassured, I will have no problem donating
