Well, powering up on insertion would certainly solve the problems of
charger indication (if we booted) and charging (if even U-Boot gets to
run) alright.  The question is if we can actually get the CPU running in
all cases.

You're saying that you don't think we can ever bring the CPU up at all
if you have a battery in there that is < 2.5V?  No matter what buttons
you're pressing?  Or just auto start from USB insertion is then broken?
~ Or all of this only happens if we disable charging from the previous
