That wont help anything here, this is pre device init stuff..

That would be a gross hack, the spec says to wait 31 secs and thats it,
if you want to wait shorter go ahead and change your local sources, but we
need to find a real solution (and I will get there, I just need enough
datapoints to find the right solution)...
