Quoting "Jonathan Nieder" <jrnieder@gmail.com>:
Perhaps there's not as much noise in the air any more. ;-)
That's the only sensible explanation :~) I tested both linux-image-2.6.32-trunk-686 2.6.32-5 from http://snapshot.debian.org/archive/debian/20100201T042505Z/ (last change 2010-01-10) and linux-image-2.6.32-5-686 2.6.32-38 from squeeze w/o updates (last change 2011-10-02). WiFi just works in both cases. I suggest to put no more time in reproducing this bug and assume that with any >= squeeze kernel everything is fine. Many thanks anyway!
