As discussed on IRC, 1/4 confused me. It should be squashed into 3/4 to make 
sense.
Other than that I think we can merge this patch series.
Not that I'm a super fan of it, but I can see the use-case but don't have an 
idea how to solve the problem in a less hacky way. ;-\

Just to be sure, DT guys are also happy with it, right?

Thanks,
