Tesla on Snow Leopard

Does anyone know whether Tesla cards run under Snow Leopard?
I currently have a 285 in my machine and it works fine, but for the project I’m working on I’d like to have two Tesla cards in there. I understand I’d probably need to rig an external power supply, but do the cards have functioning drivers?
If the cards work at all can I use OpenCL or only CUDA (I’d prefer OpenCL if possible)?

thanks,
Josh

Tesla cards do not work under MacosX, they are missing EFI support.
