sure 
i added 

atapicam_load="YES"
hw.ata.ata_dma="1"
hw.ata.atapi_dma="1"

to my /boot/loader.conf

dmesg complaints like:
da0: < > Fixed Direct Access SCSI-0 device
(da0:ata1:0:0:0): Unretryable error

if i try mount /dev/da0 /cdrom , i obtain kernel panic with "atapi_pool
called!" message

how to figure it out?
thanks
