3.1-rc9 wifi problem

[werner]

A laptop of a friend, which worked always with wifi until 
3.0.4 , stopped to work when installing 3.1-rc9 , after 
re-installing 3.0.4 wifi returned to work.  I think it was 
a packard-bell laptop.   I can't test this better because 
he gone with his laptop; perhaps next week he'll visit me 
again. Since 2.6.38 his laptop worked with my wifi.

This can be a regression in the wifi drivers, or because 
of a slightly changed config. Anyway the diff of config is 
enclosed.
