no idea!
Try maybe mount that cdrom with freebsd livecd and locate /etc/master.password file, and see if root has passwd set. But since i think that project uses compressed fs it wount be so easy.

I like another freebsd 5.x livecd project called frenzy.
ftp://ftp.opennet.ru/pub/mini-cd/Frenzy-BSD/
I used it and liked it, and recommend it :-)
only thing is lack of documentation in english.
