I was fighting with that last night, and just now figured it out.  The 
user should be a member of the operator group, but also must have rw 
permissions on /dev/cd0, /dev/xpt0, and /dev/pass0... and here's the 
trick: there can be more than one /dev/pass device.  As soon as I added 
pass1 and pass2 to /etc/devfs.conf, it worked:

perm    cd0     0660
perm    pass0   0660
perm    pass1   0660
perm    pass2   0660
perm    xpt0    0660

HAL is not needed.
