Intel 3945ABG/BG wireless card | Is there a libre driver?

My first conclusion was an emphatic no, due to the discussion in this thread,

http://trisquel.info/en/856-wifi-con-intel-3945

However, that was 2009, so I thought I'd ask if anyone knows of any progress made in a libre replacement for the proprietary firmware.

It's picked up fine by the kernel, from dmesg,

[ 7.753528] iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, in-tree:s
[ 7.753533] iwl3945: Copyright(c) 2003-2010 Intel Corporation
...

with no future errors.

and in lspci,

03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

NetworkManager "thinks" it sees it, but when I toggle the wireless switch on my laptop, NetworkManager toggles from "disconnected" to "device not ready" under the 'wireless' section.

Thanks for any help.
