There is <http://cvs.debian.org/boot-floppies/i386-specials/mini-iso.sh>
which creates an ISO with base-only pkgs, from basedebs.tar.
Alternatively I wrote this little script that lets you put whichever
debs you want on there.  Tried it with the b-f2.4 flavour.  With just
the base debs on there the ISO is 31MB.  It doesn't provide any way to
automatically install non-base debs that are on the ISO, but you can
always apt-get install them once the system is up.

# You should have a dir $DEBS containing all the .debs you want on
# the ISO.  You should have at least the base debs, as listed by
#
#	debootstrap --arch i386 --print-debs woody
#
# You might populate that dir by grabbing basedebs.tar from the archive.
# You should have a copy of the boot-floppies dir from an archive in
# $DISKS, and set $FLAVOUR to the one you want on your ISO (e.g. bf2.4)
