Sorry guys, the traces are under the top surface. I could do a 
continuity check but that would be a hassle.

In windows this card requires an application for the remote to work.

I have a PCI trace from when I start this application and I can see that 
it starts polling the board. Here is a trace of activity from me 
starting the application for the remote control and then I push the up 
arrow and down arrow a couple of times.

The 4th column is the address. The board was mapped starting at 
0xDC000000 and the 5th column is the data. The sixth tell what type of 
opperation this was.
