I've had problems when mixing epel and rpmforge on an SL5 machine
when a package depends upon a package which exists in both repos
but with different numbering or features (sometimes one split the
package into several sub-packages).

My impression is that in SL6 rpmforge has dropped many of the
duplicated packages, perhaps because they are already in Fedora.

My advice would be to install rpmforge-release and epel-release
but to edit /etc/yum.repos.d/rpmforge.repo and 
/etc/yum.repos.d/epel.repo so that they say enabled=0 for every repo
and explicitly enable that repo when you wish to install a package
from either, then you can at least see what is going on.
That does mean you wont automatically get updates for these repos
so you should run
 	yum --enablerepo="*" check-update
from time to time (overnight cron job ?).
