       This is a KMS driver for projectors which use the GM12U320 chipset
       for video transfer over USB2/3, such as the Acer C120 mini projector.

Does this build with !PCI?

The driver uses some PCI functions, so it might possibly break with
randconfig. I don't think there are practical !PCI PPC configurations.

IIRC, the first PowerMacs didn't have PCI.
