So instead of 0xd2, the address (relative to our scheme) is bit shifted right one, or 0x69. That's typical to what we've seen this kind of chip showing up as, and indeed it shows up in your scan included in your ticket. It is also typical to see this kind of chip hang the bus on a probe, so it might be good to skip this address when running sensors-detect if you have that kind of trouble. Humm.. 0x4e remains a mystery. Thanks anyway for taking the time this weekend to poke around!
