OK, this is ugly but I guess necessary because we haven't solved <http://tickets.opscode.com/browse/OHAI-339> yet. In the future this should become

    # platform_version = "12.3" or "11 SP2"
    # platform = "opensuse" or "suse"
    repo_version = platform_version.gsub " ", "_"
    repo = {"suse" => "SLE_", "opensuse" => "openSUSE"}[platform] + repo_version

Grr. Notice how our platform does not help with choosing the right repo?
