Thanks. Right now the code is already a mixture of the new code and the
old code and its almost a mess. After all drivers are converted and the
old code removed then the parport code will become much simpler than
what it is now. And it will be easy to make those enhancements at that
time.

Adding Pali to the cc list.

Hi Pali,
Are you still away from your desktop with the joystick? or can it be
tested?
