If not, the whole signed-off-by thing becomes useless,
so it better be policy.

Dunno.  "acked-by" as used in Linux is only an informal
comment; if LinuxBIOS wants to formalise its usage, the
rules should be written down somewhere.

It doesn't, but it would be silly (and irresponsible)
to sign-off on something you didn't look at first.

No.  Every step in the chain into the repo needs to
be tracked or the "chain of trust" is lost.

I don't see the incompatibility?  Unless you mean that
the acked-by tags should be put into the commit; that
is a foolish thing indeed, there are many problems with
it (for example, it is easy to forget to add one of those
when you commit; not the case with signed-off, since
that's in the patch when you send it out for review
already, and a committer will add it automatically if
he has his tools set up for that).
