I think you are a bit confused with what OLPC buildrom does.  Note
thats 'buildrom' not 'buildroot'.  OLPC buildrom is based on buildroot
but has been customized for our use by Jordan Crouse of AMD.

The output of buildrom is a 1 MiB ROM image called 'linuxbios.rom'
that is ready to be programmed into the onboard flash.  It contains
linuxbios, EC, VSA code and linux kernel payload.

The qemu images are created by Redhat in a totally separate build
process and other than the fact that linuxbios.rom is included in the
images have little to do with buildrom.
