   I built my own card for my IT and had the same need as you do, to 
have the in() and out() functions.

  I found that the only way to do this is to write a device driver, which
I did successfuly a few months ago.

 Do you need help in writing the driver or do you need help in gener-
ating a new kernel.  I think I can help with either.  If its any help,
I could gather up all my source code and mail it to you.  Let me know.
