Comment 10 for bug 55232

At https://launchpad.net/ubuntu/+bug/58358/comments/13 Ben said this bug was fixed and uploaded to dapper-proposed and edgy-proposed. Presumably it will be fixed for feisty. Even if it doesn't make its way out of the proposed repos, you can do a hd-install as said for edgy at http://ubuntuforums.org/showthread.php?t=316093

Make sure you get the initrd.gz and vmlinuz images for feisty from http://archive.ubuntu.com/ubuntu/dists/feisty/main/installer-i386/current/images/hd-media/
The edgy files may not work for feisty.
