If you need a newer kernel to use that patch, I would recommend something that
runs more cutting edge for that server, maybe Gentoo or Fedora 9. I don't
recommend patching CentOS with a new kernel as you lose the main benefit for
using an Enterprise distro .. stability.
I love CentOS, but no one distribution can be everything for everyone. That is
why there are so many choices.
