[regression] iwi0 with WPA on 8.0

Good evening,

so I managed to bring my laptop up to 8.0 and after lots of ports
recompiling I'm happy to say that it's pretty stable, but iwi0 and WPA
no longer work.

during boot I get:

wlan0: Ethernet address: 00:15:00:22:26:61
iwi0: need multicast update callback
iwi0: need multicast update callback
iwi0: need multicast update callback
iwi0: need multicast update callback
iwi0: need multicast update callback
wlan0: link state changed to DOWN
wlan0: link state changed to UP

and in messages we see

Aug 20 21:00:04 roadrunner wpa_supplicant[481]: Trying to associate with 00:21:27:f3:37:37 (SSID='COYOTE' freq=2417 MHz)

...

rc.conf has

wlans_iwi0="wlan0"
ifconfig_wlan0="WPA ether 00:0f:1f:1d:a3:76 ssid COYOTE"

but I also tried this with
# ifconfig wlan0 create wlandev iwi0 (or something like that)
# /etc/rc.d/wpa_supplicant start wlan0


Any hints or ideas?

Regards Uli
