In addition we're seeing reports of non-specific exploit warnings from managed security service providers to their customers. And some rumors.

McAfee Vulnerability Information says that they have protection against exploits of MS Vulnerability MS05-051, "Entercept's Generic Buffer Overflow Protection protects against code execution that may result from exploiting this vulnerability."

ISS says they have protection out for an exploit, it's announcement is here.

NFR says they have protection out for an exploit. their announcement is here.

Here's some pre-vuln announcement facts, see the DShield data on Port 3372 scanning, ymmv.
