We're using some of the MMessage classes to register callbacks. For MNodeMessage callbacks, the first argument passed in by Maya is the messageID. If we check to see if the messageID == OpenMaya.MNodeMessage.kConnectionMade it's always false because the value of OpenMaya.MNodeMessage.kConnectionMade is 1. The actual messageID coming in to the callback is 18433. The other MMessage related IDs are also not what I expected.
Prior to 2008 I didn't have this problem. But prior to 2008 there were other issues. As I recall, the MMessage family of classes were not fully implemented back then. They seem to be fully implemented now, in that they can actually be used, but associating the IDs is a little strange, especially when working with multiple versions of Maya.
