There isn't a formal "image", but I put the following in /etc/mk.conf:

.if defined(SOEKRIS)
MKKERBEROS=no
MKKERBEROS4=no
MKYP=no
MKHESIOD=no
MKSKEY=no
#MKSHARE=no
MKCATPAGES=no
MKDOC=no
MKHTML=no
MKINFO=no
MKMAN=no
MKNLS=no
MKLINT=no
MKPROFILE=no
#MKPICINSTALL=no
MKSENDMAIL=no
MKPOSTFIX=no
MKUUCP=no
MKGDB=no
#MKGCCCMDS=no
CPUFLAGS+=-march=i486
.endif

...this allows me to use build.sh (when I set the environment variable 
SOEKRIS) to build sets with much less unneeded stuff.  I then install 
only the "base.tgz" and "etc.tgz" sets, and I get something that fits in 
about 45M.  I can get it down to about 28M if I remove some other stuff 
by hand, but I haven't formalized that yet.  (it's on my list of things 
to do!)

Hope this helps,
+j
