Argh, yes. I was wrong about that, --cdrom also expects a top level distro
path. That should be fixed though, to just allow pointing to a cdrom like you did.

If you boot off a cdrom, kernel args have no effect, since we have no way to
pass them in to the cd. Extra args only work if you directly boot a kernel.
You should be able to try using

--location http://mirrors.us.kernel.org/ubuntu/dists/karmic/main/installer-amd64/

which will do a direct kernel boot, allowing extra args.
