I have no experience in writing driver, but I can sure help in testing.
(I have a (card=1) with saa7134 on it.) Somone mentioned about the same
topic on the lirc list a few weeks ago, but there is no further input from
him yet. Maybe you can take a look at the lirc archive.
By the way how can you obtain the 'GPIO values'? Are there any linux
tools to read that?
