Quite. There's still been no indication that anyone cares about fixing 
this interface, and I'm upset that it was merged despite there being 
clear and valid concerns about it. Do we have a commitment that it's 
going to be cleaned up before final? If not, it should be pulled before 
userspace starts depending on it. The only hardware where this currently 
matters isn't going to be running 2.6.25 anyway.
