There are several knobs you can tweak to get the size down.  What I
have done in the past is adjust some of these knobs to trim stuff out
of libc that I don't need (and trim the usage of those features from
applications), and build all-dynamic-link systems.  It's amazing what
you can fit into an 8MB or 16MB CF using this approach (and it works
with packages form pkgsrc, too).

For example, you can set:

MKHESIOD=no
MKKERBEROS=no
MKSKEY=no
MKYP=no

in your mk.conf to take Hesiod, Kerberos, S/Key, and YP/NIS support
out of system libraries and programs.  You can then set:

LDSTATIC=

to cause everything to be dynamically linked (with a few exceptions,
like /sbin/init).

For graphics ... it depends on your needs.  What kind of device?  I
have been meaning to get a Qt/Embedded port done, but it's not that
high on my list right now.
