Still looking for some information on a way the kernel could detect the presence of the tuner...

it detects the lights via GPIO_GPIO22 (EMPEG_SERIALCTS), the external mute is detected via GPIO_GPIO27 (EMPEG_SERIALDCD)...

could the tuner be detected via GPIO_GPIO21 (EMPEG_SERIALDSR) ?

I will probably just build a kernel with a hack to test it later this week... but it would be nice to have some real info from someone who actually knows a way to detect the presence of the tuner from within the kernel...

Cheers
