Wireless interface disabled after upgrade to natty and reboot

[Stig Sandbeck Mathisen]

Binary package hint: module-init-tools

In the file /etc/modprobe.d/intel-3945-iwlagn-disable11n.conf, the line
"options iwl3945 11n_disable=1" prevents loading of the iwl3945 module in natty.

This fails, on kernel 2.6.38-7-generic, with the following error message in the kernel log:
 iwl3945: Unknown parameter `11n_disable'
