Serial numbers are only printed out when you boot with -v.

You can also get the serial number of your disk with camcontrol.  e.g.:

# camcontrol inquiry da1
pass1: <IBM DGVS09U 03B0> Fixed Direct Access SCSI-3 device 
pass1: Serial Number       13102562NC
pass1: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing Enabled
# camcontrol inquiry da1 -S
      13102562NC
