FreeBSD8.0, VirtualBox-3.0.51: user cann't use CD/DVD

[Rill]

Host DVD/CD access:

I add "perm cd0 0660 " to /etc/devfs
# kldload atapicam
# pw groupmod vboxusers -m user

Root can use CD/DVD to install OS, but User cann't use CD/DVD to
install OS. User only can use ISO to install OS.

I think this may be a bug for virtualbox-3.0.51.r22902_2
