"RHEL Desktop Workstation (v.5 for 32-bit x86)" child channel has bad checksum

Currently, all of my RHEL5 i386 Workstations are doing this:

[root@kettle ~]# yum clean all
Loaded plugins: rhnplugin
Cleaning up Everything
[root@kettle ~]# yum update

All RHEL5 i386/x86_64 Servers and RHEL5 x86_64 Workstations are updating happily.

Anyone else having issues?

All the computers have active subscriptions with RHN. One, which had lost its child channel subscriptions owing to temporarily having been downgraded to "Update" rather than "Management" entitlement, was prepared to update until I readded the "RHEL Desktop Workstation (v. 5 for 32-bit x86)" child channel to depsolve some packages, at which point I got this:

Error: failed to retrieve repodata/00c88bd13aefb00b56c228e899f418a0ace9a077-filelists.xml.gz from rhel-i386-client-workstation-5
error was [Errno 14] HTTP Error 404: Not Found

Which is subtly different, but still indicates some kind of issue with this child channel.
