I could.

I suddenly saw no activity anymore in libertas-2.6, just later I 
heard that you were in Mongolia. So I posted my stuff as before.

John, I saw that you pushed one bugfix patch upstream, but not 
the others. Please don't apply them, I'll put all ACKed patches 
into the libertas-2.6 tree instead.
