Thank you for report. Problem is that atapicam provides fake emulated 
SPI transport, but not a native ATA in terms of updated CAM. Small 
attached patch fixes this for me:

# camcontrol devlist
<OCZ-VERTEX 1.30>                  at scbus0 target 0 lun 0 (pass0,ada0)
<Slimtype DVD A  DS8A1P CA11>      at scbus3 target 0 lun 0 (cd0,pass1)
