Ok, it was not that hard. It follows my comments.

As already discussed, instead of removing, just print some warning if people
use this parameter. The printed message should ideally direct to some wiki page
commenting about the changes, and explaining how to emulate the previous
behaviour where such parameter were needed.

There are several bttv boards without tuner. In fact, those are becoming
a more common setup with bttv, since there are still several surveillance
boards with bttv being selled in the market. We should test if !TUNER_ABSENT
before doing the probe for a tuner.

Why aren't you probing first at I2C_ADDR_MSP3400? You're changing the behaviour
here. It is better to probe at the same order as the previous version.

Why do you need to probe it twice? Shouldn't it be just one probing for both addresses?

This is not what I call "tvaudio autodectect" (that should be the default way,
as the comments for tvaudio option states).
A bttv board should have some audio chip otherwise audio won't work.
I dunno if is there any supported card without audio at all, but probably, if
we have, this is by far much less than boards with an audio chip.
Based on this principle, IMO, the probing function should, by default, probe
for tvaudio, if it doesn't find another audio device. You may eventually ask
for people to report, to warn us that the board entry is broken, but we
shouln't intentionally break a device that we're almost sure that requires
tvaudio or tda7432.

We should preserve the same probing order as before, in order to reduce breakage risks.

No audio module found. This requires printing a warning, since the board won't have audio working.
