I've booted a stripped down (but not minimal) kernel with
hw.physmem=3D10M to single user, but couldn't even get to multi-user
with 16M: Too many processes and too much swapping (I didn't trim my
enabled list on my laptop). If I booted a minimal kernel, and did
some creative trimming, I think I can get down closer to 6M to 8M on a
fairly small system (no acpi, etc), but it would be painful to run in
that environemnt, unless you had special needs (eg, it was an embedded
platform).
