Are you sure about
that? /usr/share/initramfs-tools/hooks/flash_kernel_set_root should be
setting a fallback root in the initrd, so if the command line doesn't
have root= I think things should still work.

When that comes homefully we can upgrade in a backwards compatible way.
I suppose/home it might be as simple as:
        if test -z ${device} ; then
            setenv device mmc
        fi
instead of the unconditional setenv. That assumes that the uboot env
would then set $device to scsi, but that seems pretty conventional
nowadays.
