I thought this was actually addressed in 7.10, ...from my notes changes I made 
before I upgraded to 8.04:

Create a file called /etc/modprobe.d/blacklist-ipw3945 and add:

blacklist ipw3945

Add to /etc/modules:


Reboot. After the system restarts, verify that the module iwl3945 (and not 
ipw3945) is loaded:

$ lsmod | egrep 'Module|iwl|ipw'

You should see an output that looks like:

Module                  Size  Used by
iwl3945                88168  0
iwlwifi_mac80211      175112  1 iwl3945
cfg80211                7304  1 iwlwifi_mac80211

As seen, only the iwl3945 module is loaded.

This is the card in my Dell laptop and it works fine with Ubuntu.  There is 
one little help I found to make connections more sure and to the WiFi point I 
wish to use called WiFi Radar.  I have three neighbor's points around my 
house plus my own which the laptop will automatically connect to, so 
sometimes I want to change over to mine as I want to access parts of the home 
network, plus mine is a "g"  rather than "b" connection.  :)  :)  At the 
office there are 6 plus my own.  WiFi Radar make selection or changing easy!

Hope that helped, BTW- my wireless shows up as eth1 and the wired (hardly ever 
used on this laptop) as eth0.
