Is iwn drivers working on Current ?

Hi,

I try to use the iwn drivers on my Dell Latitude D630 laptop on a
up-to-date current, but I can't.

I've an Intel 4965AGN card, and here is the result of pciconf -lv :

iwn0_at_pci0:12:0:0:	class=0x028000 card=0x11218086 chip=0x42298086
rev=0x61 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel 4965AGN Intel Wireless WiFi Link
4965AGN(supporting 802.11a/b/g/Draft-N)'
    class      = network

I've put on /boot/loader.conf the magics lines:
legal.intel_iwn.license_ack=1
if_iwn_load="YES"

my /etc/rc.conf is configured like that:
wlans_iwn0="wlan0"
ifconfig_wlan0="country FR WPA DHCP"

and the /etc/wpa_supplicant.conf was tested using 2 others differents
wirelles card (USB rum and PCMCIA ath) without problem.
But I have this error message on dmesg:

iwn0: need multicast update callback
iwn0: error, INTR=2000000<SW_ERROR> STATUS=0x0
iwn0: error, INTR=2000000<SW_ERROR> STATUS=0x0
iwn0: iwn_config: configure command failed, error 35
iwn0: iwn_init_locked: could not configure device, error 35
iwn0: iwn_config: configure command failed, error 35

iwn0: iwn_transfer_firmware: timeout waiting for first alive notice, error 35
iwn0: iwn_init_locked: could not load firmware, error 35

(The wireless switch is on the ON position, and this wireless works
when booting with Linux Ubuntu).

And not association possible...

Here are some other information:

Does someone know where the problem is ?

Thanks for your help,
