As Johnny already pointed out in his post - the kernel-sourcecode rpm 
that you generate using this method will not really be the kernel source 
that reflects the real state of the binary kernel.

Try building a kernel out of this source, compare with the binary kernel 
built out of the .src.rpm and the point is easily demonstrated.
