How big does your compressed kernel get to? I can only get my 5.x
kernel.gz to 508k at the moment. Removing snapshots code may get me
back another 10k or so. Removing PS/2 mouse gets me 15k or so.
atapi-cd gives me about the same.
loader uses 83k, but I haven't tried to remove anything there.

I have this hack for ssh on 5.x. Put:
/--
ssh_rsa_OBJS= rsa_eay.o rsa_intlstubs.o
ssh_OBJPATHS+= /devel/obj/usr/src/secure/lib/libssh/libssh.a
ssh_OBJPATHS+= ${ssh_rsa_OBJS}
LCRYPTO= /usr/src/crypto/openssl/crypto
rsa_eay.o: ${LCRYPTO}/rsa/rsa_eay.c
${CC} ${CFLAGS} -I${LCRYPTO} -DPIC -i $@ -c $<
rsa_intlstubs.o: ${LCRYPTO}/rsa/rsa_intlstubs.c
${CC} ${CFLAGS} -I${LCRYPTO} -DPIC -i $@ -c $<
ssh.lo: ${ssh_rsa_OBJS}
\--
in crunch.inc, and crunchgen -h crunch.inc, and append ".include
crunch.inc" onto the Makefile. Adding ssh makes fs.PICOBSD.gz grow from
496k to 737k! I use 'progs ssh' and 'libs -lssl -lcrypto -lrsaINTL'.
