The VP-3040 is a bit different kind of card, as per my knowledge it has 
a detachable add-on CA board, and can have TS188 as well as TS204 too.

I need to add some more code to correctly identify this board..
Temporarily you can try force it to use TS188 (DST_TYPE_HAS_NEWTUNE) or
TS204 (without the NEWTUNE option) and see how it goes..

Possibility is that probably the Tuner type will be the other case what
is exactly for you at the momemt and hence communication errors..

Let me know how this goes .. You will need some more patches, i will
post it a while later in the night .. In the meantime you can check out
which tuner type works appropriate for you .. (You should not see any
i2c communication errors, except in the case of a very weak signal, if
you gone through the right steps)
