Hmm, well ignore the above.  I'm not sure how I came up with that
bisect.  At the moment, I'm having trouble with all the roms using
--enable-kvm, and it seems to point at commit 132c3917.  But I would
have sworn they were working for me on Friday, so I don't have much
faith in my build environment today.  I'll save any more speculation
until I can figure out how things were working before.  Thanks,
