Yes, I can say it will not work.
The code in the arch/ppc/mbxboot directory, which is used for
all 8xx and 8260 processors, assumes there is memory above 4 MB
it can use for buffer space while decompressing the kernel. You
can play around with adjusting these addresses and sizes, and get
a kernel to boot. You will get a shell prompt, and that is about
all. You won't be able to use a ramdisk, you probably won't be
able to execute any useful programs.

I like MMUs because I don't have a real life.
