Comment 6 for bug 597068

Starting with Oneiric, the linux-firmware package contains these files (http://kernel.ubuntu.com/git?p=ubuntu/linux-firmware.git;a=commit;h=d1cadcf6c2df78f865e0433b3a8ee9a7420a9042). Could you confirm that this works for you?

(if you're not running Oneiric yet, installing the package from https://launchpad.net/ubuntu/oneiric/amd64/linux-firmware/1.60 should do the trick)
