ok, as far as i can see for now, it looks like the actual solution is 
ignoring/rejecting any manual command to set parameters, neither 
iwconfig nor iw will change any settings. wpa_sup brings the card up and 
does also WPA2 but nothing else is tuneable thus a connection via 1Mb/s.

attaching a tarball from the results of the script which produced 42 
files of output.
