I thoroughly dislike the ever-more bizarre combinations of alphanumerics that are being required for passwords, even for sites as simple as a forum. I found the article below after getting in a heated discussion about the matter with the IT department of a particular site. (It was the first hit on a google search of "usability" and "passwords".)
http://www.baekdal.com/articles/Usability/password-security-usability/ Basically, the author discusses how passwords can be both more secure and more usable by using a string of 2-3 common words rather than a single word containing random alphanumerics. I'm not sure it deals directly with your question regarding a usability threshhold in password strength, but you may find it useful for an alternative perspective on the issue.
