Hi Hartmut,

that was just some fallout in between and I`m sure to have the proper
testings already. That checksum game is interesting, but whatsoever is
such hidden something good for, except to cheat.

What gives me more to worry about recently is, that it is hard for me to
"illuminate" some last working status of the saa7134-empress in some
variant I have currently. (I'm down to bit specific operations)

If pioneers like Geert, Greg or Mans could provide me with some
saa7134_i2c debug on _start_ last known state and setting the fmt
successfully, might help.

Cheers,
Hermann
