I like that. It's a little potential extra bookkeeping, but not much, since you can check previous posts. It has the potential to give you infinate rages, but that would be a long day 
I would adjust one thing. You should have to be consious at the time. I can see a rage saving you from going unconsious. but think of the Barb that was 5 below half to start, gets knocked unconsious, and bleeds down to -5, should he suddently wake up because his con increases and he's positive again because of a rage?
I did like the rage tree, but I think it was a bit too powerful. I think you could eventualy create one though.
