Giveio uses some kernel mode driver that finally boils down to inb() and
outb(). As wine can't load the kernel driver, no Parallel port access
happens.

Two posibilities:

- Write a substitute for givio.dll that uses the wine way to access the
  parallel port
- Write a wine layer that can load windows kernel drivers.

If the interfaces for giveio is available, the first task ins't too hard.
The second task is more challenging...
