OK, I'll give this a shot. I tried just adding ipw3945 to the blacklist
and then running modprobe on iwl3945 and this loaded the module fine,
but it doesn't fit into the system well. Network Manager doesn't work
and the interface name is wlan0_rename.

What other steps are necessary to integrate this driver into Ubuntu
gutsy?

Odd. I can't recall having to perform any other steps. Have you
tried restarting NM or restarting? Don't forget to add iwl3945 to
/etc/modules if you try rebooting.

Is there anything useful in dmesg or /var/log/messages when you
modprobe iwl3945?

I don't remember any either. Here are the notes I used:

Description: When using the ipw3945 wireless module, the network connection
can drop or lockup during heavy transfer rates.
Impact: Wireless connection drops. Data transfer stops.
Workaround: Use network module iwl3945 instead.

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

Add to /etc/modules: iwl3945

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. Hope this helps! It was easy
enough the even I could do it! Of course it was done on a laptop which
had "Gutsy" factory installed.
