Hi,
I'm still thinking that problem is in driver - under Windows everything seems 
to be ok. So I've tried to capture i2c bus between stb0899 and stb6100 and 
got things like this:

Start of driver - linux

More captures are available - if somebody is interesting in, I'm ready to post 
it.

All captures are done within the same hw environment with i2c monitoring 
interface from http://ivtv.writeme.ch/tiki-index.php?page=Monitoring+I2C+Bus.

BR,

Ales
