Hmm... Did you realize that the same code is driving the remote for both 
of these cards?  I applied this to cvs three weeks ago... Maybe this 
should be changed...  Based on the rest of this thread, it sounds to me 
like there might be slightly different GPIO going on...

        * saa7134-cards.c: (saa7134_board_init1):
        * saa7134-input.c: (saa7134_input_init1):
        - enable support for the IR Remote on Compro Videomate T200
