Comment 25 for bug 180544

Krazyd, sorry I missed your query until I had the same problem crop up yet again after an upgrade, due to the fact the Ubuntu devs are still ignoring this bug :-(

Save the patch into your home directory, then it's just two steps:

# Apply the patch
sudo cat ipw200-initramfs-firmware.diff | patch -p0
# Update the initramfs with the needed firmware
sudo update-initramfs -u

Keep the patch around as you will have to do this each time initramfs-tools is updated.
