Godofwar, try these tutorials for Lion:

http://www.insanelymac.com/forum/ind...owtopic=278181 (I got it to work using this one)

http://www.hack-my-mac.fr/index.php/...fx-buldo#28896 (this is very good also)

Back up your Snow Leo before trying any of them. Report back, we're all helped when we know that something really works and how (by the way, hey, xmaniak!, did the drivers work?).
