Here are four logs from doing:
scandvb -a1 ./e.1
where the contents of file e.1 are:
S 11919000 V 27500000 3/4
which is probing a region on the Eutelsat-9A satellite broadcast.

The four logs are:
(1) DVBSky's megapatch: I2C traffic generated by cx23885 module initialisation
and probing.
(2) DVBSky's megapatch: I2C traffic generated by the aforementioned scandvb
command.
(3) Antti's drivers plus my S952 glue: I2C traffic generated by cx23885
module initialisation and probing.
(4) Antti's drivers plus my S952 glue: I2C traffic generated by the
aforementioned scandvb command.
The scandvb command with the DVBSky megapatch gave:
