They have also stuck an +infra-red remote control decoded on the board, I will add support for this +when I get time (it simple generates an interrupt for each key press, with +the key code is placed in the GPIO port). + +I don't yet have any application to test the radio support. The tuner +frequency setting should work but it is possible that the audio multiplexer +is wrong. If it doesn't work, send me email. + + +- No Thanks to Leadtek they refused to answer any questions about their +hardware. The driver was written by visual inspection of the card. If you +use this driver, send an email insult to them, and tell them you won't +continue buying their hardware unless they support Linux. + +- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw) +who make the audio attenuator. Their publicly available data-sheet available +on their web site doesn't include the chip programming information!
