Check the archives of wine-devel.  There was a rather lengthy discussion of 
this problem and what may be required to fix it.  Perhaps the DFly team would 
be amenable to the changes. :)

Quoting a message from John Birrel on this thread:

It was determined that wine should not be changed at that it would likely be 
better to change FreeBSD's mmap address allocation algorithm.  The thread is 
called "Wine on FreeBSD current".
