I use these shell functions under 2.0_RC4 without trouble:

# iso images
function mount-image () { vnconfig /dev/vnd0 $1; mount /cdrom2; }
function umount-image () { umount /cdrom2; vnconfig -u /dev/vnd0; }

in /etc/fstab:

/dev/vnd0a /cdrom2 cd9660 ro,noauto 0 0

disklabel reports that there are 'd' and 'a' partitions, but no 'c'.

This is on i386; it looks like the i386 special treatment for c/d is
getting applied, but no 'whole disk' partition is being created.
vnd(4) is silent on this matter.
