Definitely a problem. I believe you're out of luck, Linux/ARM and in fact
any Linux needs an MMU. It's a pretty fundamental component to having
seperate address spaces and protected resources.
There is a strange beast called uClinux (micro-controller Linux) which
runs on m68k and z80 CPUs without MMUs. Everything shares the one address
space; the user space memory allocator has been hacked into the kernel
space allocator etc. I've seen a demo running on a Pilot, quite bizarre.
I don't believe there's any intention to have an ARM uClinux port, but you
never know. If you really want to run Linux on something without an MMU,
that's the place to start.
Hope that helps.
