The reason I don't just make it a local repository is two-fold, first off, I don't think I'd be able to pull it through since without the driver I can't see the array in order to install, and secondly, this won't be used by me locally, I intend to host the respin on our work servers for customers to use if they have this particular controller that doesn't have native support. Basically making my life easier not having to walk people through the driver install several times a week.
I had a chat with people in #centos recently. They are a bunch of jerks and they are unlikely to be helpful to you, but you could still try asking there for help. It is your best chance, even if the chances that they will attempt to be helpful are slim.
