Thanks again for this suggestion. I do feel it's getting me closer to
having Coreboot boot to Debian with FDE on the X201. However, there's
still a way to go...

Based on your suggestion above, I kept everything as described in my
first email in this thread, except that to build Coreboot, I also
selected "Use native graphics initialization" under "Devices" within
`make nconfig`. (This sets CONFIG_MAINBOARD_DO_NATIVE_VGA_INIT=y in
the .config .)

Unfortunately, my results were exactly the same as before, except that
this time the backlight came on. In particular, no GRUB2 prompt
appeared.

Is this expected? From your email, it sounds as though it isn't what
you expected.

I would be grateful for additional suggestions from you or other
experienced Corebooters :)

Thanks again!
