That's ok.

we might written the wrong value into dmidata. (dmidecode reads a
description written by the firmware, has nothing to do with the real
values).

tp smapi depends on lot of SMM/SMI code. So tp-smapi kernel module
asked the Lenovo BIOS to tell the EC to do something. coreboot don't
want to support SMM/SMI APIs, because they are quite dangerous.
But there is another way to get those features back.
We know how to enable it, but we haven't yet create a way to control
this by the user.
One thing could be a userspace tool executed as root or we add another
CMOS configuration for it. Any idea?

It looks you're using the native graphics init instead of the binary
blob VGABIOS. The last time I tried it, I had a lot of problems. [3]
Thanks for your feedback. Feel free to create tickets or updating the
x220 wiki page.
Best,
lynxis
