rt-kernel in a Remix?

[constanton]

Hello,

I am going to create a Remix for Music/Video production, analysis etc.
At the wiki, I 've seen some other attempts like this one:

htt p://fedoraproject.org/wiki/Music_Creation_Lite_Spin (sorry about the space in the link, forum doesn't let me post otherwise)

It also provides a kickstart file, which I don't quite follow on how it imports a real-time kernel !
The thing is, I am planning to use the Planet CCRMA repo for Fedora 15 x86_64 to include the rt-kernel...My question is how is this possible?
The kernel is right here:

htt p://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/15/x86_64/repoview/

Thank you!
