Have we crossed some boundary where we're going to need tools to systematically reverse engineer the EC now? Maybe we need to start accumulating EC knowledge on a new coreboot.org page ... I am realizing I don't understand them at all.
coreboot.org or flashrom.org? The goals are pretty different. Each needs EC interaction, but coreboot doesn't care about being able to flash and usually has people who can dump the chip, while flashrom cares very much about being able to flash and nothing else.
I tried to explain the EC situation from a flashrom perspective: http://www.flashrom.org/Supported_hardware#Unsupported_Laptops.2FNotebooks.2...
Information about the EC used in thinkpads may possibly be gained from tp_smapi: http://www.thinkwiki.org/wiki/Tp_smapi The project has a thinkpad_ec module so they may have a method of reliably detecting the beast :-)
