It wouldn't be ES 4 then. The way the enterprise releases work is that 
no software is upgraded, therefore you don't find new and exciting 
changes in the way things work. Instead, any bug fixes or security 
patches are backported to the original software.

ES is intended to provide extremely stable platforms for production 
servers, which normally doesn't make it a good candidate for building 
new kernel modules.

I assume that's why ES is being used.
