There are three things that need to be done here:
1) Adapt the bus interface.  This is not too much work and should boil 
down to a couple of sed(1)s and a few manual edits.  Check drivers that 
are in OpenBSD and FreeBSD and compare, or just check existing drivers.  
The DRIVER(9) manual page and jmg@'s paper[1,2] should provide additional 
insight.
2) Use firmware(9) to load the ucode - as far as I understand the device 
needs firmware as well.  This shouldn't be much work and can be taken 
verbatim from iwi(4).
3) Adapt the net80211 interface.  This one's a bit tricky since OpenBSD 
went a different way with their 80211 implementation.  Again, looking at 
existing drivers (esp. ath(4) as the reference implementation and iwi(4) 
as a driver from OpenBSD that was also retrofitted into FreeBSD) should 
give an idea what is done how.

In the end, you won't know what problems you come across until you start 
with it.  I can help with questions regarding 2 & 3, but will be busy for 
the next two months and don't have a 3945 to test with, either.
