Cool.

I have a house rule that I use though: if a PC takes enough damage to be "dead-dead" (not just negative), then the other PCs have 1 turn to get to him and bring him up high enough that
raise dead is not required later.
I justify that by saying that actions in combat are simultaneous and therefore it's reasonable to let other PCs get one action. Of course, I don't like metagaming so asking "how negative are you" is out of the question. In my home games, a question like that means any healing won't help (you've angered the gods, so to speak!).
This really increases the tension level when a comrade goes down during combat!! And there's no metagaming so having a PC drop unconscious at just -1 is treated almost like being at -20! But overall the players realize that they're getting an extra action to avoid the cost of
raise dead and appreciate the house rule.
Probably can't use it in PFS as there aren't supposed to be "house rules", but using the justification above it could be viewed more as an interpretation of the initiative sequence and not a rule change. Pages 24-25 of the 3.5 DMG talk about simultaneous actions in more detail and basically just leave it up to the GM.
