Now, if we've had to change the contents of the DTS because of a kernel
change, I'd say the DTS format changed as when I say format I mean not
only layout and naming, but what the contents are supposed to contain.

And, so it's clear, I don't know if we're at the very stable format
(names/layout/content means...), but when we are at that point, what
Matthew noted should, IMHO, be a graceful (ie explained in the panic()
or something) death.

And, so it's clear, I think (and hope!) we all agree on that last part,
once we hit stability.
