That kernel image is too large.
We did lift the limitation on kernel size of 4 MiB a while back (commit
486df8bc4627bdfc ("m68k: Increase initial mapping to 8 or 16 MiB if possible")),
but that still requires the first memory chunk to be at least 8 or 16 MiB,
which rules out booting kernels larger than 8 MiB in ST-RAM.
