Ah, sizzle chest, I checked the Apple Knowledge Base (Wasn't it so much simpler - and much more Apple-like - when it was just the Apple Tech Info Library?) and you're right, the programmer's button is used in the update process. For the rest of the Mac line-up, it's just the usual "hold down the three-button salute, wait for the long bong, and release".
