There is on "other" Unix type OS's the command "eject" which
will actually open the CD tray. I use it all the time in the
server colo when there is some mislabed machines, I'll make sure
all the CDROM trays are shut, login to the machine and type
"eject" and the tray of the mislabed machine will pop open.
Here is some information that "may or may not" help you in
finding a *BSD equivalent:
