I tried again, this time with SeaBIOS instead of GRUB2 as the primary
payload, and with CoreInfo as a secondary payload. As above, I
selected "Use native graphics initialization" under "Devices" within
`make nconfig`. (See attached .config .)

The result was the same as above: the backlight came on, but there was
nothing displayed on the screen.

I do think you are probably right about this issue (i.e. nothing being
displayed on the screen) being due to a failure to initialise the
graphics properly, and I am open to further attempts to overcome the
issue, as my time allows.

Is there anyone on the list who has Coreboot working on an X201 who
would be willing to share their .config file, so that I might see how
they succeeded where I am failing?

Thanks!
