No, they're not; flags is an extra 4-byte param in qemu-kvm-1.0, which
doesn't exist in qemu-1.0.

In qemu-2.1 -M 1.0, "flags" got renamed to "channels[0].irq_disabled",
which is also flagged.

You're looking at the wrong output.  You should see one message back,
where I compare qemu-1.0 with qemu-2.1 -M pc-1.0.  That has the
piix4_pm version mismatch flagged.
