And is it a bug that people are hitting? Yes, without that patch iwlwifi devices are not able to connect with some old APs. I had only two Fedora bug reports about that, so do not think this is something critical. Fill free to drop that patch (together with "iwlwifi: manage QoS by mac stack" which is part of the fix and do not have sense alone), or apply only to 2.6.34.
