You can use it via a suid-root wrapper program that acquires the port access, 
drops privileges and executes your wine programs. Works for me. Of course it 
doesn't work if the windows program needs the special driver to talk to the 
device. It does work for those old-style windows95 applications that expect 
to be able to talk to the ports directly.
