Wine does not support this type of drivers. They can not and will not work on Wine. You can not access hardware ports on Linux from user space unless you running this program as root. Or used some other mechanism to allow yourself to access ports. Even if you running program as root, you still have to use ioperm() to enable port access. For more details see for example this HOWTO: http://tldp.org/HOWTO/IO-Port-Programming.html
