I've been looking into this issue (from a usability perspective it affects some
other things I'm working on), and it can be fixed without forcing users to
continually edit their /etc/hosts file.  First, a knowledge base article on how
they intended this "feature" to work:
http://support.microsoft.com/kb/160215

As a result of reading that article a light-bulb went off for me, this command
is intended to return all the addressable IPs (or in unix parlance, the IP
associated with each unique route) in order from highest to lowest priority. 
So, after digging through RTNETLINK a bit I was able to create a small example
application that does this (obtains each unique route and gets the associated
IP, though RTNETLINK reports routes from lowest priority to highest).  I
believe that this is a legitimate route to obtain the behavior desired by
Windows without forcing users to edit their /etc/hosts file every time their IP
changes.  If this sounds acceptable then I can whip up a patch that will do
this if Wine would otherwise have reverted to the "magic IP."
