[coreboot] Supported laptops (again), treacherous computing

I'm looking for an x86_64 laptop to try Coreboot. I've looked through
the archives [1,2] and the wiki [3]; it seems the most popular machines
are x60s and t60.
However, these machines are shipped in different configurations [4,5].
This page [6] mentions Core Duo Mobile L2300, which has a 32-bit
instruction set [7], so I'm not really interested. And this one [8]
says about Core 2 Duo T7200 [9] and Core 2 Duo Mobile L7400 [10] (each
has a 64-bit instruction set). Is there a configuration that doesn't
require non-free [11] components? It's not clear from this page [12].
And this answer [13] is a bit confusing because it just mentions x60,
not a particular configuration. Is there a need to worry about
microcode or EC? Are there any plans regarding them? For example, even
"the first fully free laptop" has freedom-related issues with EC [14].
Also, this processor [10] has so-called embedded options. I'm a bit
concerned. I don't have any personal experience with such technologies,
but these links [15--19] are scary. Could anyone elaborate? For
instance, this page [16] says that one can remotely enable AMT even if
it was disabled in BIOS. Can Coreboot permanently disable such
"features"? Can it disable DRM [20]?
TL;DR: I'm looking for an x86_64 laptop that should work with Coreboot,
shouldn't have nasty "features," shouldn't refuse to boot if I replace a
component, and shouldn't require non-free software to run.
