     The pninek is a color frame buffer with graphics acceleration, embedded
     in the Tadpole SPARCbook 3 laptop. It is based on the Weitek Power9000
     video processor and a Brooktree Bt445 'Chameleon' RAMDAC.

     Due to specifics of the video hardware on the Tadpole SPARCbook 3, the
     complete driver is split in two parts:

     btcham  RAMDAC interface
     pninek  Video controller interface

     The combination of both btcham and pninek drivers interfaces the frame
     buffer with the wscons(4) console framework. They do not provide direct
     device driver entry points but make their function available via the
     internal wsdisplay(4) interface.

     If the tctrl(4) device is also configured, the pninek will be powered
     down when the lid of the laptop is closed or the screen is blanked.
