@naquaada: Did these kexts work for you in 10.5.2 rev2 or are you using rev1 or 10.5.1??
I switched to Leo4All but the problem did'nt go away. At least that release has working network shares... I really need the graphics to work. It's the only thing missing in my setup..
It seems alot of other 71c2 users on 10.5.2 are having similar problems.
