I will never ever ever ever ever... ever understand why, while house ruling the barb rage to end while unconscious people don't take the step in the proper direction and house rule that the hit point gain are lost first instead of temporary (I don't remember the exact name of such hit points... those the vampiric touch spell gives).
If you rule that the rage end at -1, a wise barbarian will drop the rage at -5ish + 2*levels hit points. In other words, no effective gain of hit points (unless you gamble getting a cure before reaching -1). In such case, the only effective gain is +2 Fort save (which isn't that good since barb already have a good fort save) and a gambling possibility to get a few more hit points. At this point, you're better off house ruling that the rage only gives +4 str and no con bonus (since they are irrelevant).
Where the players got the real shaft with such a system is not when the players plays a barb. It's when the DM does. Since the barb NPC is disposable, the DM's barb will get the extra hit points and not the player!
That's why the rage still go on while unconscious.
