i2c_hw=1 causes bttv to use Hardware I2C instead of S/W based 
Bitbanging. I think the HDTV5 uses S/W I2C

I think individually it can be called as card=0x68/0x71 i2c_hw=1 
card=0x87 i2c_hw=0
Maybe Greg could try that addition and try it like that and see how it 
goes .. ?

ie modprobe bttv card=0x68/0x71 i2c_hw=1 card=0x87 i2c_hw=0
