They don't. FreeBSD without 386 support runs in VMWare and qemu. Bochs
is dying as far as I can tell. I feel that removing support for 386 is
fine, and my understanding after reading this thread is that we're
worried about embedded platforms, and it seems that most of these that
we run on are already 486 or higher.
With regard to the instruction set clones, I've run post-386-debacle
FreeBSD (and seen it run) on several clone boards including the Via
embedded stuff and Geode stuff.
My understanding of how this got into the embedded chipset stuff was
that a suggestion was made to deprecate 486 as well, which I don't
think we should do at all. Get rid of 386, support 486+.

It is a big problem for recent embedded hardware. Until the
pentium-based embedded boards get cheaper, it's still nice to have
cheap-ish 486 boards, and these will _not_ go anywhere for a while,
especially since their price will fall more if the pentium boards get
cheaper.
