Are you loading lirc_i2c? It loads bttv, rivatv, ivtv and cx8800. This 
is pretty bogus IMHO and causes problems.

For example, I have an nvidia FX5200 with video-in (no tuner). I don't 
use the video-in for anything but lirc loads rivatv which grabs the 
hardware and prevents the nvidia graphics driver from being loaded.

Because of this I had to recompile lirc from source with this patch:
