You're free to do whatever you want with your Linux distribution, but if you're not using the thing that the vendor supports, they're not going to support it. There's not really any way around it. Unfortunately the kernel has significant and widespread implications on the system, so it's very hard to figure out how to support a system that is running a kernel version you haven't validated. As a RH customer, the way I handle this kind of thing is usually by replicating the problem on a "stock" system and working with RH support on fixing it on that system --- this is often an important step anyway since, for my own purposes, I need to figure out whether or not I introduced the problem by something I did.
