Hi Greg! Thanks for chiming in.

Let's take these out in v2 then.

It is my understanding that bridge drivers are the ones responsible for 
this. For instance, I don't see this with either xc4000.c, xc5000.c or 
mt2060.c. I could be wrong, though. Maybe Mauro could clarify this?

What I did miss in this patch was an attach function. Let's also add 
this in v2.

Thanks again,

- Daniel.
