Well, it *is* optional -- but the kernel as we build it needs an
initrd to do much that's visible.  Could probably enable fb console
and provide a commandline that points console there (-c "kernel
commandline"  argument to fastboot).

Is a uImage compatible with zImage (if the bootloader copies it to
0x10008000 and jumps there will it start?)

Ah, I see.  Yes, renaming the files would be easy to do and that's
totally reasonable.  I thought you wanted the machine type name
changed.
