Using the ATAPI/CAM Driver

I've enabled the ATAPI/CAM driver in my kernel under freebsd 5.2 - this has
given me two devices: /dev/cd0 and /dev/cd1. Thus far, I'm able to burn
CDs/DVDs but I am having trouble mounting them (as root).

If I issue the command: mount /cdrom or mount -t cd9660 /dev/cd0 /cdrom I
get the message:  cd9660: /dev/cd0: Device not configured


However, if I comment out the /dev/cd devices in fstab and enable the acd
devices:

/dev/acd0               /cdrom cd9660   ro,noauto       0       0
/dev/acd1               /cdrom1 cd9660 ro,noauto        0       0
#/dev/cd0               /cdrom cd9660   ro,noauto       0       0
#/dev/cd1               /cdrom1 cd9660 ro,noauto        0       0

I'm able to mount w/o problems.

Do I have something misconfigured?

Thanks,
