That is what a fixit CD is for (or one of the many things).
Just boot up your fixit CD and wend your way around the menus
of choices until you get a prompt.   Or, for that matter, do
the sliceing and dicing from sysinstall on the fixit.
For FreeBSd 4.xxx and before the fixit is disk 2, I believe
and for FreeBSD 5.xxx and after the fixit in CD number 1.
