Hey, I have a Dell and it still "mostly" works...
The 1st gen iPod I have was given to me broken (fell off a car on the highway at speeds of 60 mi/h). The HD was bad and the original battery was simply old. A new HD fixed the machine, and the new battery was added as a bonus (new chemistry, longer runtime). Unfortunately those were the only things broken on it and I never had to test the battery charging circuit or anything else. If I did have to fix those I would know more about how it works.
There /is/ a chip, but it doesn't "speak". It only protects the battery during charge/discharge. Kind of like a smart fuse. It has no outside communication. I thought battery life was estimated in software and learned the battery behavior. I believe the main guts of the iPod only regulates the firewire 12V down to something like 5V, then the chip on the Li+ battery regulates the power going into the battery. I'm sure the MAX1555 is a similar chip:
