Hi,
Since i2c was added to the kernel, I have sometimes trouble with my bttv
card. Before that, I never had any trouble with bttv since kernel 2.2.0.
The modules are loaded when I start X with vidmode extension turned on. When
everything goes well I see the following in my syslog:
kernel: Linux video capture interface: v1.00
kernel: i2c-core.o: i2c core module

Except that I don't know which aliases to use for the tvmixer. What are they?
Anyway, when it goes wrong I see:

I can fix this by manually removing the bttv module, before starting XawTV.
But when I don't do that, next will happen:
