I think the kernel also has to be within the ROM-readable part too.  If
you cp the kernel into / (as opposed to mving it, if you build your
kernels on that filesystem), it will often wind up entirely in cg 0 and
thus below the 1G mark, but this is a risky thing to depend on.

Or a separate boot partition, with / elsewhere, typically with a kernel
configured "config root on" the actual / partition.
