Well, my processor does support mmx, so I don't see any reason why it
should do this.  Unless there's some extra configure option to only enable
mmx and not mmx2 that I'm missing.  Also, the crash only happens when im
running entrance and it would seem that by doing so, a bug in entrance or
evas is making evas think that i have an mmx2 capable processor.  By the
way the crash results from an illegal instruction.
