1) Check that iw reports that you can do it (I just now committed code
   to iw to report it since you asked, so use git version, which will
   become 0.9.23 at some point in the future)

2) get git version of wpa_supplicant, compile with CONFIG_IBSS_RSN and
   use a config file like this:

ap_scan=2
network={
	ssid="your SSID"
	mode=1
	frequency=2412
	proto=RSN
	key_mgmt=WPA-PSK
	psk="your secret key!! :-)"
}


If you find a good place, maybe you can add it to the wiki?

Note that wpa_supplicant currently doesn't reject the config if the
driver doesn't support it, but it won't work.

If you want to make your driver support it, the easiest way is to
implement something like I did for iwlwifi:
