The kernel side is fairly easy if you have a couple of megs of ram. The
ucLinux tree supports mmuless systems and a fair variety of processors. 
User space is more of an issue. The standard Linux userspace is designed
for systems with disks and paging, the uclinux stuff is smaller and the
ELKS userspace is tinier still.

And uclinux is free not $200. Maybe the writer is confused with the 
ucSimm development board ?

BTW are "real" 16bit processors actually cheaper any more ? 16bit keeps
costs down but several 683xx processors seem to use 16bit external
data bus as do some ARM.
