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
Due to specifics of the video hardware on the Tadpole SPARCbook 3, the complete driver is split in two parts:
- RAMDAC interface
- Video controller interface
The combination of both
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
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.

There is currently no way to switch back and forth from the onboard display to the external connector.
It is not possible to change display resolution.
Acceleration code does not work correctly, and is therefore disabled.
