While I can't speak for specific features in the redhat kernel, I have taken the config file that comes with a CentOS kernel and applied it to a kernel.org kernel using make menuconfig. I then went quickly through the options added in the more recent kernel and selected reasonable values for them. The resulting kernel ran just fine, but, as I said I was not trying to use any new features added by redhat. Note, that you want to build the new kernel under the CentOS release that you'll be running it under. Perhaps you could apply a procedure similar to this using the RedHat 6 kernel instead of a kernel.org kernel (building with the CentOS 5.x or whatever config file and then changing the options that you want to change - you might have problems if you try to enable features not supported by older lib files).
