It works, but everytime I do an upgrade I start to sweat, quite often the card "dies" and I have to login from another machine with ssh, kill X, unload and reload the kernel module. Wish you good luck :-) -r PS: for the sake of knowledge, debian wheezy here -- L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.
