up2date -i nagios-plugins-*; or, how to exclude a package from just one particular repository in up2date?

With yum on e.g. CentOS 5, I can put custom exclude= lines in to a specific repository configuration, which still allows yum to get those packages from other repositories.

On my RHEL4 ES system using up2date, however, it seems that the /etc/sysconfig/rhn/sources file only allows excluding packages entirely (from all repositories); and it seems to not care about what I put in the repository configuration files in /etc/yum.repos.d/ 

Here's my specific problem: I inherited this system from a previous sysadmin, and as I found it, the up2date sources configuration file includes the dag apt repository (yum dag http://apt.sw.be/redhat/el4/en/$ARCH/dag), and the epel repository(yum EPEL http://download.fedoraproject.org/pub/epel/4/$ARCH).

Here's what happens when I try to install nagios-plugins, etc using up2date:

# up2date -i nagios-plugins{,-disk,-mysql,-load,-dns}
