Are you using GRUB as the boot selector, or something else?
(I'm interested because I'm preparing something similar.)

Yes, I've done a DVD9 with several BSD variants on it.  You
can put FreeBSD in a subdirectory; it does _not_ have to be
in the root directory of the DVD-ROM.  You don't have to hack
sysinstall, it already searches several possible directory
names, for example the name of the release ("5.3-RELEASE").

You can find the appropriate code at the end of the file
src/*/sysinstall/media.c (where * is "release" for FreeBSD
4.x and "usr.sbin" for 5.x).  In short, it searches the
following directories, relative to the media base:

        /
        /FreeBSD
        /releases
        /$RELNAME
        /releases/$RELNAME

where "$RELNAME" is the release name (e.g. "5.3-RELEASE").

Best regards
