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?

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.
