problems with wireless using iwi drivers

Hi,

I'm new to FreeBSD-CURRENT and am having problems getting my wireless
to work on my laptop. It is an old Centrino ASUS laptop with built-in
IPW2200 wireless. I've had no problems getting wireless to work on
this for the past few years now with many flavors of linux and of
course Windows so I'm sure it should also work in FreeBSD without any
issues.

However, I'm not having much luck. I've followed the instructions in
the Handbook's Wireless page and read the iwi(4) man page and added
the following to my /boot/loader.conf:

-------------
legal.intel_iwi.license_ack=1
if_iwi_load="YES"
wlan_load="YES"
firmware_load="YES"
iwi_bss_load="YES"
iwi_ibss_load="YES"
iwi_monitor_load="YES"
hw.psm.synaptics_support=1
--------------

When I reboot and do a "dmesg | grep iwi" I get:

----------
iwi0: <Intel(R) PRO/Wireless 2200BG> mem 0xff9de000-0xff9defff irq 4

Am I forgetting to load the firmware somehow? In /boot/kernel, I see
the following files:

-----------
[root_at_asus ~]# ls -l /boot/kernel/iwi_*

But if I try to do "ifconfig iwi0 up" I get:

----------
iwi0: timeout waiting for (null) firmware initialization to complete
iwi0: could not load boot firmware (null)
----------

Any help appreciated. Thanks.
