Give me a few minutes, I am going to try to fix the driver kext.
OSX 10.7.4 breaks the "MAGIC " support.
I have a feeling that Nvidia will release new drivers for 10.7.4 soon, but until then I will figure out and post a fix.
EDIT: OK, here is a quick fix. This will enable the driver to include GTX570 and GTX580.
I will do one for GTX560 later on.
If you were using the ""self init" feature, you will also need to install ATY_Init from Netkas.
If you had one of our EFI cards, this should do it by itself.
You will need to use Kextdrop or Kexthelper to install this once you unzip it.

If you are using an EFI card, you will have one screen still functional to "see" from while you install this. If you were using the "Magic" feature, the card will be black as night until you install this fixed next AND ATY_Init.
If you were using Magic Drivers to run a GTX4xx card, you don't need this fixed kext, just ATY_Init.
