There's a patch circulating around that enables the required firmware
binary, but please talk with bschmidt@ because I think he has a very
good idea about tests you can run with 802.11n features.

The attached patch fixes iwn(4) for me on my Asus Zenbook laptop, and it
does associate correctly to my home AP, but please use with care. I
haven't extensively tested high traffic situations or an exhaustive list
of 802.11n features.
I'm happy with it for casual home use of my laptop, but please report
any problems you may find...
