This provides support for Cuda/Egret based Macintosh and
Power Macintosh systems. This includes most m68k based Macs,
most Old World PowerMacs, the first generation iMacs, the
Blue & White G3 and the "Yikes" G4 (PCI Graphics). All later
models should use CONFIG_ADB_PMU instead. It is safe to say Y
here even if your machine doesn't have a Cuda or Egret device.

If unsure say Y.
