It was only broken for me attempting on freshly installed post-dboot bits,
so BFU'ing post-dboot may not reproduce the problem. But this isn't stock
ON, so there might be a problem on my end; I'll reattempt the experiment
sometime this week...
Also: is the qemu-system-x86_64 considered ready for prime time? I would
much rather use that if it's considered to be beyond the experimental
phase...
