Dave just got referenced in a talk at the 30th Chaos Congress in Hamburg.
In a talk about how to secure a laptop by ripping out all the potentially problematic parts (not that much remains... ;-) the part where the speaker showed how he took apart the device and did the deed had Daves motto "Don't turn it on, take it apart!".
In case you are interested, the talk is titled "Hardening hardware and choosing a #goodBIOS", by Peter Stuge. The video recording may take a bit of time to become available though.
