Since coreboot is an alternative of BIOS, does this mean to use coreboot, people will have to flash coreboot on to these boards? And each time coreboot updates, these boards will require a reflash? If that's the case, it sounds like testing coreboot leaves a lot of room for error.
ME:
Intel's Management Engine
Handles lots of things related to the BIOS, and allows for some fancy (and creepy) enterprisey-features if your laptop supports VPro. It's more or less a second computer inside your computer dedicated to a small number of things.
Here's Flashrom's page on the ME: http://flashrom.org/ME
That plus wikipedia should give you a good background on it.
EC:
Embedded controller
This handles lots of power, fan, and temperature stuff for your laptop. It keeps your laptop from frying itself, regulates the fan accordingly, and depending on the model, does backlight / keyboard control.
Coreboot has a good bit on Embedded controllers, especially in laptops: http://www.coreboot.org/Laptop#Embedded_controllers
Both of these make it hard to support a laptop with Flashrom, let alone Coreboot.

You can get motherboards with dual BIOSes but yes it's risky for most.
