Uhm... leave out the "mode 11b" part. You don't have to do anything
to force 11b mode (especially since most Centrino NICs are 11b only
anyway).

Just do:

# ifconfig ndis0 inet 10.0.0.1 netmask 255.255.255.0 \
	ssid CATCUS mediaopt adhoc up 

I have gotten ad-hoc mode to work on the Centrino with my home network
(it was the first thing I tested) so you ought to be able to get it
to connect. Be wary of getting too clever with setting media options with
ifconfig on if_ndis at this point: it needs work.

The two things which I know will work are:

# ifconfig ndis0 mediaopt adhoc		<-- select adhoc mode
# ifconfig ndis0 media autoselect	<-- select BSS mode

If it doesn't associate right away, you might try doing
"ifconfig ndis0 down; ifconfig ndis0 up" once or twice to reset it,
though in my tests I don't think this was necessary.

Also, the only useful thing you can do with wicontrol(8) at this
point is an AP scan:

# wicontrol -i ndis0 -l

The only reason wicontrol does this is... er... well... we don't have
any other standard utility in FreeBSD that can do it.
