I can confirm this bug - it happened to me after an upgrade a few days ago too. I got "Module is unknown" messages when typing a username into the login prompt (it didn't even prompt me for a password). Had to boot into single mode, change every occurence of "pam_unix2.so" and "blowfish" into "pam_unix.so" and "md5", respectively, in /etc/pam.d/*, then set new passwords for the users in order to replace the blowfish hashes by md5 hashes in /etc/shadow.
