Vladimir was describing a potential method of automatic testing of
GRUB in the absence of an XO, using an emulation stack consisting of
qemu, coreboot, and Open Firmware.  This would allow the testing to be
done on almost any build machine used by the GRUB project.

But the stack didn't stand up.

Another potential method is qemu running the OLPC Open Firmware
directly, but this also doesn't stand up ... because qemu lacks
emulation support for XO.  I did think of adding it but didn't get
around to it.
