You can look to see what the size of your Redboot is
and then load the kernel (zImage) just above it and
then load the ramdisk just above the kernel. Don't
forget to update the kernel command-line to point to
the new ramdisk location. For example, you could try
to load the kernel at 0x00030000 and the ramdisk at
0x00230000.
IIRC genext2fs will only generate ramdisks up to 8MB.
You may need to search for an update/patch.
