The thing we learned the hard way, is that on some hardware, you cannot set
up the graphics twice unless you do a reset in the middle and that is
difficult and sometimes impossible.

For one distro we did, webboot, we would always kexec another linux.

We found that, if we wanted graphics in the first linux with x11, we could
make the kexec of the final linux with x11 work with qemu, and not with
hardware; or with hardware, but not with qemu. It was a mess.

The fix in the end is never enable graphics until the last linux boots.

Just a data point, not sure that helps.

I can say the coreboot graphics init worked on many chromebooks. But Intel
fought it tooth and nail, so I also know it did not work in all.
