We had that 4 years ago or so. Want me to look up the code?

corebootPkg boots the Fedora 19 Live DVD on QEmu.

Could you try on real hardware? I'm away from mine for the next couple 
of days.

edk2 source with (some) documentation can be found at
https://github.com/pgeorgi/edk2/tree/coreboot-pkg

The image above was built with the GCC47 toolchain, the 64bit issues it 
had are now fixed.

Like Duet, the resulting payload should be portable across boards since 
coreboot does the initialization part.
CSM is useful to initialize video if you only have a PCBIOS style 
VGABIOS (eg. on QEmu).
