Was this supposed to read "does not make significant changes" ? Looks
pretty minor to me (outside of jumping kernels :).

For what its worth our other x86 testing should have largely covered
this. If we can't count on the transitive value of our testing using
the common fragments/drivers/arch, then we don't have much to count on.

I see little risk in this myself, and would support the default changing
to linux-yocto in 1.0.1.
