I had some (litle) time to try again with that box.

I noticed that I can connect that box to eduroam wifi network with 
gnome-network-manager and 2.6.32, but still have the problem with normal 
wpasuplicant roaming use under 2.6.32, something that worked (with some 
disconnections) with 2.6.26. Seems I have to look more carefully at the 
logs to try guessing what is the reason for this different behavior.

I will try more once I have access to that box again. Unfortunately this is
not in a daily basis.
