I personally have more than two optical drives on two of my computers attached to the same IDE controller on the same cable but it is not recommended!!!

Make sure that pins on the back of your Pioneer are in master position and that pins on you ASUS DVD ROM are in slave position.

Check if the devices properly detected by BIOS as a master and slave.
If not you have a hardware problem. I suspect that one of the devices doesn't work on UDM66 cable.
Check then the dmesg Try to mount CDs on the devices manually before altering fstab.

Also you can read this regarding DMA IDE. It is for OpenBSD but it should
be similar in FreeBSD
