"Off-topic" even, yes ;)

We knew of a similar problem between i2c-viapro and via686a. I didn't
know that i2c-viapro and via-ircc had the same problem. And I guess that
i2c-viapro and vt1211 would conflict too?

Mark D. Studebaker is working on a solution for i2c-viapro and via686a.
I don't know if the same solution will apply in the other cases. Since
i2c-viapro is involved in all three conflicts, it promises to be damn
complex...
