I think JELTKA is a model of how it can be done. Consider talking to John Lewis.

As long as you keep the 32bit entry point around, yes (which I think
is the default configuration for x86_64 kernels).
In kconfig/menuconfig/..., select a linux payload, and point to the
bzImage file. That should work (and this part of coreboot is pretty
well testable with our QEmu targets, in case you want to try it out
first).

Sadly documentation is not a strength in this project.

The kexec information there is probably still useful, the buildrom
stuff is horribly outdated.
