virtualbox and cdrom

[Martin Smith]

I have installed virtualbox on a stable system of 26 June.
Loading vboxdrv from loader.conf is fine, no panics, creating a vdi goes 
well,
and then, it cannot see the cdrom drive, it says the cdrom is always 
secondary
master, but this board only has one ata channel. I have tried setting it as
primary master, but no dice.
Any workaround for this, or have I missed something silly.
It is an Asrock mobo, with one ata and 4 sata ports.
