Unfortunately, the way almost all drivers/media/[video|dvb] was made,
the IR (and input support on webcams) are tighted to the driver.

It would be possible to change it (and it is not that hard), but it requires 
people with enough time and skills to go into each driver that can support IR, 
split the IR code into a separate module and be sure that the driver will 
compile and work with or without IR support.
