I think you wil still be better off with amd:

# cp /usr/share/examples/amd/amd.conf /etc
# mkdir /etc/amd
# cp /usr/share/examples/amd/cd /etc/amd
# cp /usr/share/examples/amd/net /etc/amd
(the net map is for NFS client access - /net/{host}/fs ... ; take it
out if you don't need it)
# mkdir /net /cd /amd
( /etc/amd/cd needs to be edited - by default it uses cd{0,1}a, one
needs cd{0,1}d on i386 and amd64; I personally modify it to contain
only

/devaults type:=cdfs;opts:=ro,nosuid,nodev
0 dev:=/dev/cd0d

 - I have only one CD drive)

(edit /etc/defaults/rc.conf to enable amd, rpcbind and the nfs daemons
- the latter if you have left the net map intact and expect to be
using nfs client; restart)
