Just a heads up that iwi(4) in -current now requires the 3.0 firmware. We still can't include this in OpenBSD due to licensing issues and the driver currently isn't too picky about which version it attempts to load.
You will run into some odd errors if you try run older versions with -current. Damien offers a prepackaged version of the firmware on his site designed to be used with the pkg tools. http://damien.bergamini.free.fr/iwifw/OpenBSD/iwi-firmware-3.0.tgz
