ARMEL on low power mmu-less platforms?

[John Griessen <john@ecosensory.com>]

Awhile back I see in the archives:

From: Riku Voipio :
--------------------
Now to expand our userbase, the easiest way would be to replace the
versatile kernel with something else qemu supports. We want kernels
that:

1) That the hardware is actually suitable for Debian - Enough storage
space and RAM, reasonable CPU and a MMU.
------------------

I am just wondering if any kind of debian subset even can be put on a 
machine without MMU?   I'm not just interested in these for cost alone, 
but for low power networking in remote places -- sensor networks,
so the cortex-m3 ARMv7-M CPU is great for that, and one silicon chip 
from luminary has precision time protocol another great reason.


Since linux-arm has a cortex-m3 linux port (using uclinux methods), I 
wonder if there is any possibility or interest from debian in these kind 
of constrained machines that could never do graphics, just server functions.

Thanks,

John Griessen

PS  Even if this doesn't fit normal debian goals, I'd like to hear about 
what it is like to port from a minimal linux install, 
(http://www.linux-arm.org/LinuxKernel/LinuxM3)  to ARMEL or just enough 
to run apt...
