Well, there is a Linux port for MMU-less devices
(http://www.uclinux.org/) that is quite usable,
but of course the lack of MMU brings some
limitations similar to eCos.
I wanted to say that an application where the virtual
memory is _needed_ (for example because you are
allocating memory in a way that the fragmentation
would create problems and can't cange that) needs
a full-blown Linux.
Whether the device itself has or does not have
a MMU is not so important here. A MMU-less device
can run uClinux and a device with a MMU can
run eCos.
