Well this is turning into a lesson for me. There are a few that used to be non-free until newer versions came along:
Apple Public Source License - was nonfree before 2.0
Artistic License 1.0 was nonfree. 2.0 is.
Reciprocal Public License - FSF doesn't indicate a revision, but OSI shows a version 1.5.
Without history it's not clear weather these were OSI approved before revision. There are also some in the OSI list that are not on the FSF list, so I'm not sure if they're free or not.
But I still stand by my second assertion that most of them are unnecessary. If you're not BSD/MIT compatible and not GPL/LGPL compatible, your code will probably have a limited life.

OSI has history. All licenses approved by OSI are either on the current list [0] or the superceded list (where the originator of the OSI-approved licenses has indicated it should not be used for new work) [1].
