Thanks,

I fetched the 20070923-freebsd-wpi.tar.gz tarball, built both modules, 
set the sysctl and rebooted.  The driver is very verbose and dumps 
thousands of lines to the console and /var/log/messages.  I was able to:

# ifconfig wpi0 ssid Imagination
# dhclient wpi0

However, when I attempted to access the network, my system became 
completely unresponsive and I had to power off.  I've attached, what I 
hope are, pertinent parts of messages.

===> dmesg
