The Avermedia Cardbus (E500 - SAA7134_BOARD_AVERMEDIA_CARDBUS) doesn't have
remote control as far as I know. The first model was Cardbus Plus (E501R)
which is not supported (yet), but Grigory Milev reported that it works with
small patching. I plan to send patches after some more testing.
Cheers,
Oldrich.
