I have a case open with MS on this. I will post the solution once we have determined root cause.

So, we were able to get the system writer back by following This was listed in the thread referenced above by Razmus, but still the WMI writer does not show up and TSM definitely seems to want it on this server. Interestingly, we have other 2008 servers backing up with TSM where the WMI writer does not show up, but they work just fine. I'm wondering under what circumstances the WMI writer is called for. The server in question here is clustered. I'm wondering if WMI us a requirement of the cluster config...?

OK, so after getting the system writer to show up with, all that was needed is a restart of the WMI service and that fixed the issue completely.
