I suspect you're hitting a bug in DKMS regarding the installation of
those 'installed-weak' modules that was resolved with a later version,
but that hasn't been pushed to the software repos on linux.dell.com
yet.

Would you mind installing
http://linux.dell.com/dkms/dkms-2.0.19-1.noarch.rpm, and manually
fixing up dkms's database the way you want (e.g. dkms
install/uninstall commands)?  On next kernel upgrade it
should work as expected...
