I think that you are taking the "ICE" thread out of context. What matters in case #1 isn't the same for case #2. Normally any info is good info. But it has to be where we can see it. I like the card around the neck and ID braclets are good. I agree with Polak in that if I need an airway you are getting on. Things I would include on a card.
1. Name
2. Meds
3. Major problems(his. of mi, tram. intubation, etc.)

Just my .02
