I have used the NDIS wrapper in FreeBSD and Linux few times for a couple 
of different systems. Generally for things I could not choose the 
hardware for for whatever reason.  It does the job for the most part.  I 
think in one particular case  i got the impression that the driver had 
to remain closed due to some FCC restriction on the radio being used.   
With the exception of video(Intel), what other areas of hardware are 
lacking support in FreeBSD? And would the same approach make sense for 
those?

I specifically excepted Intel video because this is an area that is 
currently under development and it requires significant changes to the 
kernel.  From what I understand Intel wrote the open source GEM kernel 
module for Linux under an MIT type license.
