I could be mistaken, but I was under the impression that adhoc only 
supported B or G speeds, and that if you wanted N speeds, you have to 
use STA rather than ADHOC.

I've heard this discussion outside of relation to FreeBSD, so I know 
it's a well-discussed issue.  I also think I remember reading something 
about certain chipsets supporting 11n in ADHOC mode, but only when 
connecting to other chipsets. I think it was MAYBE an atheros chipset, 
but I don't really remember -exactly- what I read, or where it was...

Here is a linux ath9k forum post regarding it:
http://comments.gmane.org/gmane.linux.drivers.ath9k.devel/2660 Seems to 
indicate that 11n in ADHOC isn't supported there either.. Sooo....
