Looks like the updated MP for Biztalk is now live in the catalog.  We're now at version 6.0.6411.0 and changes include:

• Addressed an issue where discovery was not fully working when host instances had multiple parent hosts.
• Addressed an issue where discovery was not fully working on systems using a locale other than US-English.
• Removed the dependency on the base BizTalk management packs from the Microsoft BizTalk 2006 R2 RFID Management Pack.

You can download the updated Management Pack from the catalog here.

Enjoy!
