Well, to follow up to my own post, I finally got the drive working.  It 
seems FreeBSD would refuse to detect the drive if it was in the master 
position.  Switching it over to slave on the ATA channel allowed FreeBSD 
to detect it, even though there is no master on that channel.  I didn't 
even think this was legal with ATA.  Anyway, the drive probes fine now 
as ata1-slave.
