Well, if regressions are found while I test the stuff, I'd try to fix 
the bugs that cause these regressions, possibly discussing with upstream 
in the process.

If regressions are found after it makes its way into Precise, well, if 
there are just a few, I could have a look at them myself and try to 
track them down (if anybody else, such as yourself, want to help out, 
that's of course welcome too!). In the unlikely event that the 
regressions are huge and terrifying and more than we can bear, we'll 
take the decision to back the patch set out.

Btw, an additional motivation for bringing it in is that "Having 
independent volumes for speakers and headphones" [1] was one of the top 
brainstorm suggestions a while ago.
