Two tenured professors at the University of Uppsala, Oleg Viro and Burglind Joricke, were forced to resign in 2007. The reason seems to have been a disagreement with the rector of the University, Anders Hallberg, over an appointment of an applied maths professor. (As far as I know, there weren't financial reasons involved, but still I thought it might be worthwhile to mention this here.)
