Thanks for the ideas, Seth and James.  It turns out I overlooked
something simple.  I've been playing with CentOS so long, I forgot
RHEL's $releasever includes the "Server" or "Workstation" string.  I
changed my mrepo config to create "rhel6Server-x86_64" and
"rhel6Workstation-x86_64" and the yum $releasever works great in that
case (i.e. "rhel$releasever-$basearch").
