I am not sure if this is feasible. I've read the section "building an external module with older kernels" in http://www.linux-kvm.org/page/Code, but I am not sure if that applies to my x86_64 architecture. RHEL kernels differ heavily from the Linux upstream kernels that have the same version numbers. kvm-kmod likely assumes that some interfaces are missing, but the RHEL kernel actually have them. You will have to identify these difference and adjust the wrappings of kvm-kmod accordingly. I would accept patches.
