In linux kernel since version 2.6.27 (release Date: 2008-10-09)  
The BT8xx frame grabber chip has 24 GPIO pins that can be abused
as a cheap PCI GPIO card.

This chip can be found on Miro, Hauppauge and STB TV-cards.

The card needs to be physically altered for using it as a
GPIO card. For more information on how to build a GPIO card
from a BT8xx TV card, see the documentation file at

If unsure, say N.
