How difficult would it be to port the ral driver from FreeBSD?

Good, I'll get net access on Wednesday (I just moved), 
and I'll get the drivers then from FreeBSD and OpenBSD, 
and I'll use them as a reference to get started. If I have 
any questions, I'll ask the list, but If the API's haven't 
changed much, then I don't think the task is beyond me.
