 I've been playing with this a bit and have gotten mine to work
 reliably in the house here connecting to an ad-hoc network. I'm just
 using iwconfig and ifconfig
 
 iwconfig eth2 essid blah
 iwconfig eth2 key restricted s:foo
 ifconfig eth2 up

also need (for my ad-hoc config) 
iwconfig eth2 mode ad-hoc

one more thing I've learned, at least for my steup: power saving
doesn't work. If I set any of the power-saving modes I get lots of
dropped packets, no web access, and my ssh sessions lockup until I
turn it back off.

Update on: How to wifi with ipw3945 on Dell Vostro ???

I still cannot wifi with my laptop but I can see that the laptop is
sending it's DHCP requests to the network, I can see the request being
answered by the server but somehow/somewhere the the response gets lost.

If I try to make a connection through the NetworkManager I see (using
tcpdump) the following traffic.

Questions about what I see:
- What are those oiu Unknown things I see?
-Are the lines with ethertype Unknown (which all seem to be from foreign
(== not mine) MAC addresses) from other AP's in the building?
- If so, could they interfere somehow with my dhcp requests?
- Why do I see IP6 things while my  whole network is IP4?
