As pointed out by others, SL kernels are rebuilds of the upstream (RHEL) kernels, so cannot be modified by SL developers. You could rebuild the kernel with the fixes yourself if that is technically possible. But in this case, as far as I can see, the provided patches are against later kernels and are not easily applicable to RHEL/SL kernels.
You can do one (or both) of the two things. One is to file a request at http://bugzilla.redhat.com with a detailed description on why the patches are needed. The other is to try and use kernel-ml [1] from ELRepo. That will let you run the latest mainline kernel from kernel.org on SL 6. There is a good chance that the patches are already in there (not checked yet).
