16MB should be quite usable for even a recent NetBSD. I wouldn't recommend compiling
using a recent *gcc* in that amount of RAM, but otherwise the system should be fine [*].
4MB would boot but probably not run anything useful in a timely fashion :). Certainly it
runs on a variety of m68k machines where 16MB was a common capacity (mac68k, sun3, etc).
I suspect the code for the motorola VME SBC could be a reasonable place to start (

[I've run X under NetBSD on a Dreamcast in 16MB with root & swap over NFS, but
that was more proving a point :]
