Hi,
Don't know if this has already been figured out, but this article may be useful in implementing proper AC adapter identification in Mac OS (and there's next to no info on the "ACID" SMC key on the 'net):

The key is just a 1-wire 64-bit ID, and the link breaks the ID components down very nicely.
EDIT: Thank you to whomever moved this to the correct place.
