Sounds reasonable, however I wonder if this is a temporary issue that  
impacts a handful of ports.  Do you know if there are many projects  
apart from wine that need 32-bit?

I'd say that, if it does impact several ports to go for it.  If it's  
only wine or one or two other ports, I'd leave things as they are and  
post it as a known bug.
