The simple answer is no. We (Alan) packages the upstream kernel as is. 
If you want a newer version, run a newer kernel.

As you have seen below, whilst the RHEL kernel may have started out life 
as a 2.6.32 kernel, Red Hat are constantly updating it by backporting 
newer versions of drivers, and as you note below, the RHEL kernel now 
uses a newer version of the megaraid driver that the 3.10 kernel. So in 
this case, if al you are interested in is the megaraid driver, you are 
better off sticking with the distro "2.6.32" driver than using the 3.10 
elrepo kernel.

No point in this case Brian, as all we will ever do in this case is 
package the upstream 3.10 kernel source. Hope that helps.
