A glance at the bat book tells me the exception (no masquerading) is 
  inserted by

EXPOSED_USER(root)

Doh! I see it now. FreeBSD doesn't do it this way (so no "CE root").

For FreeBSD, non-masquerading for root is simply set by an entry in 
/etc/mail/exposed-user-names, which is brought in by the 
EXPOSED_USER_FILE directive in the default mc file. Edit 
exposed-user-names to your heart's content (and pay attention in 
case mergemaster throws it back at you during upgrades), and all 
should be well.
