Comment 37 for bug 352440

I can arrange something to give you the initrd I just made to test. I was using the netboot i386 version (booting off PXE).

We won't be going in production with a custom fix like this but at least the operating kernel has the right modules.
This major issue (network driver aimed by this bug report isn't loaded) that could be solved by a minor fix.

For your medias, check hardy's release schedule and you will notice there is no more point releases. You will have to wait for the next LTS which is in 2 months.

Check out Ubuntu's documentation on building the installation medias. Pretty much everything is well documented and you only have to follow the steps.
