The sl-addons repo has a fixed zfs-modules-dkms package now.

you will want to run a 'yum clean expire-cache' to catch the updates.

Since DKMS is in EPEL6 where it is actively maintained, adding it to SL Addons 
would create work on maintenance without adding much.

It does make loading some packages more complex,
